Description
The JHW250-series dc-dc converters are a new generation of DC/DC power modules designed for maximum efficiency and power density. The JHW series provide up to 250W output power in an industry standard Half-brick, which makes it an ideal choice for high voltage and high power applications. The converter incorporates synchronous rectification technology and innovative packaging techniques to achieve ultra high efficiency typically 92% at 30.2V with full load. The 5-sided encapsulated case package allows for excellent thermal performance in strict thermal environment. Threaded or nonthreaded-through holes are provided to allow easy mounting to a cold wall or addition of a heatsink for high-temperature applications. The JHW250 series power modules are isolated dc-dc converters that operate over a wide input voltage range of 36 to 75 Vdc and provide single precisely regulated output. The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. Built-in filtering for both input and output minimizes the need for external filtering.

Fusing Considerations CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 15A for JHW250 series (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer's data sheet for further information.

Test Configurations
Design Considerations
Input Source Impedance
The power module should be connected to a low ac-impedance source. Highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 13, a 200F electrolytic capacitor (ESR<0.7 at 100kHz), mounted close to the power module helps ensure the stability of the unit. Consult the factory for further application guidelines.
Output Capacitance
Note: Measure input reflected-ripple current with a simulated source inductance (LTEST) of 12 H. Capacitor CS offsets possible battery impedance. Measure current as shown above.
Figure 13. Input Reflected Ripple Current Test Setup
Output capacitance and load impedance interact with the power module's output voltage regulation control system and may produce an 'unstable' output condition for the required values of capacitance and E.S.R. Minimum and maximum values of output capacitance and of the capacitor's associated E.S.R. may be dictated, depending on the module's control system. This series power module requires minimum of 1000F output capacitance placed near output pins to ensure stable operation in full range of load/line conditions. The process of determining the acceptable values of capacitance and E.S.R. is complex and is loaddependant. Tyco provides Web-based tools to assist the power module end-user in appraising and adjusting the effect of various load conditions and output capacitances on specific power modules for various load conditions.
Note: Use a 1.0 F ceramic capacitor and a 1000F aluminum or tantalum capacitor. Scope measurement should be made using a BNC socket. Position the load between 51 mm and 76 mm (2 in. and 3 in.) from the module.
Safety Considerations
All Versions - For safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., UL60950, CSA C22.2 No. 60950-00, and EN 60950 (VDE 0805):2001-12. "W" Versions only - For end products connected to -48V dc, or -60Vdc nominal DC MAINS (i.e. central office dc battery plant), no further fault testing is required. *Note: 60V dc nominal battery plants are not available in the U.S. or Canada.
Figure 14. Output Ripple and Noise Test Setup
Note: All measurements are taken at the module terminals. When socketing, place Kelvin connections at module terminals to avoid measurement errors due to socket contact resistance.
All Versions - For all input voltages, other than DC MAINS, where the input voltage is less than 60V dc, if the input meets all of the requirements for SELV, then: The output may be considered SELV. Output voltages will remain within SELV limits even with internally-generated non-SELV voltages. Single component failure and fault tests were performed in the power converters.

Remote On/Off
One pole of the input and one pole of the output are to be grounded, or both circuits are to be kept floating, to maintain the output voltage to ground voltage within ELV or SELV limits. "W" Versions only - For all input sources, other than DC MAINS, where the input voltage is between 60 and 75V dc (Classified as TNV-2 in Europe), the following must be meet, if the converter's output is to be evaluated for SELV: The input source is to be provided with reinforced insulation from any hazardous voltage, including the ac mains. One Vi pin and one Vo pin are to be reliably earthed, or both the input and output pins are to be kept floating. Another SELV reliability test is conducted on the whole system, as required by the safety agencies, on the combination of supply source and the subject module to verify that under a single fault, hazardous voltages do not appear at the module's output. All Versions - The power module has ELV (extra-low voltage) outputs when all inputs are ELV. All flammable materials used in the manufacturing of these modules are rated 94V-0. The input to these units is to be provided with a maximum 15A, (JHW250 series) fast-acting fuse in the unearthed lead. Two remote on/off options are available. Positive logic remote on/off turns the module on during a logic-high voltage on the ON/OFF pin, and off during a logic low. Negative logic remote on/off turns the module off during a logic high and on during a logic low. Negative logic, device code suffix "1," is the factory-preferred configuration. To turn the power module on and off, the user must supply a switch to control the voltage between the on/off terminal (Von/off) and the VI (-) terminal. The switch can be an open collector or equivalent (see Figure 16). A logic low is Von/off = 0 V to 0.8 V. The maximum Ion/off during a logic low is 50 A. The switch should maintain a logic-low voltage while sinking this 50 A. During logic high, the maximum Von/off generated by the power module is 5 V. The maximum allowable leakage current of the switch at Von/off = 5V is 10 A. If not using the remote on/off feature, perform one of the following to turn the unit on: For negative logic, short ON/OFF pin to VIN(-). For positive logic: leave ON/OFF pin open.
Figure 16. Remote On/Off Implementation
Remote sense
Remote sense minimizes the effects of distribution losses by regulating the voltage at the remote-sense connections. The voltage between the remote-sense pins and the output terminals must not exceed the output voltage sense range given in the Feature Specifications table i.e.: [Vo(+) - Vo(-)] - [SENSE(+) - SENSE(-)] X% of Vo,nom. If not using the remote-sense feature to regulate the output at the point of load, then connect SENSE(+) to Vo(+) and SENSE(-) to Vo(-) at the module. Although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of both. The maximum increase is the larger of either the remote sense or the trim. The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using remote sense and trim: the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be
Feature Descriptions
Overcurrent Protection - Auto-Restart
To provide protection in a fault output overload condition, the module is equipped with internal current-limiting circuitry. As the load current is increased beyond its limit, the module will start to fold back its output voltage hence limiting output power. In the event of a severe overload where the output voltage is pulled lower than approximately 21V the module will enter hiccup mode to further reduce the power dissipation of the module. The module can survive a continuous short circuit. Once the overload has been removed the module will auto-restart and normal operation will resume.

taken to ensure that the maximum output power of the module remains at or below the maximum rated power.
Where, VO = Desired output voltage set point (V). The voltage between the Vo(+) and Vo(-) terminals must not exceed the minimum output overvoltage shut-down value indicated in the Feature Specifications table. This limit includes any increase in voltage due to remotesense compensation and output voltage set-point adjustment (trim). See Figure 17. Although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of both. The maximum increase is the larger of either the remote sense or the trim. The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using remote sense and trim, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power.
Figure 17. Effective Circuit Configuration for SingleModule Remote-Sense Operation Output Voltage
Output Voltage Set-Point Adjustment (Trim)
Trimming allows the user to increase or decrease the output voltage set point of a module. This is accomplished by connecting an external resistor between the TRIM pin and either the SENSE(+) or SENSE(-) pins. The trim resistor should be positioned close to the module. If not using the trim feature, leave the TRIM pin open. With an external resistor between the TRIM and SENSE(-) pins (Radj-down), the output voltage set point (Vo,adj) decreases (see Figure 18). The following equation determines the required external-resistor value to obtain a desired output voltage.

Where, VO = Desired output voltage set point (V). With an external resistor connected between the TRIM and SENSE(+) pins (Radj-up), the output voltage set point (Vo,adj) increases (see Figure 19). The following equation determines the required externalresistor value to obtain a desired output voltage. Trim up for output voltages: 30.2V

[(2 x 28) - 30.2] K (30.2 - 28)

To trim up the output of a nominal 30.2V module (JHW250S30R2) to 31.0V
31.0 Radj - up = 9.5944x (0.04056x 31.0) - 1.225 - 10 K
Rtadj-up = 9181 K
Output Overvoltage Protection - Latching
The output overvoltage protection consists of circuitry that monitors the voltage on the output terminals. If the voltage on the output terminals exceeds the over voltage protection threshold, then the module will shutdown and latch off. The latch is reset by either cycling the input power for one second or by toggling the on/off signal for one second. The protection mechanism is such that the unit can continue in this condition until the fault is cleared.
Overtemperature Protection - Latching
These modules feature an overtemperature protection circuit to safeguard against thermal damage. The circuit shuts down and latches off the module when the maximum baseplate reference temperature is exceeded. The latch is reset by either cycling the input power for one second or by toggling the on/off signal for one second. The protection mechanism is such that the unit can continue in this condition until the fault is cleared.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout limit, the module operation is disabled. The module will begin to operate at an input voltage above the undervoltage lockout turn-on threshold.

Thermal Considerations
The power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat-dissipating components inside the unit are thermally coupled to the metal case. Heat is removed by conduction, convection, and radiation to the surrounding environment. Proper cooling can be verified by measuring the case temperature. Peak temperature (TC) occurs at the position indicated in Figure 20. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel. For reliable operation please refer to the power derating guidelines shown in figure 21. Under no circumstances should the absolute maximum temperature at this point exceed the 100C threshold.

Layout Considerations
The JHW250 power module series are encapsulated aluminum case packaged style, as such; component clearance between the bottom of the power module and the mounting (Host) board is limited. Avoid placing copper areas on the outer layer directly underneath the power module. Also avoid placing via interconnects underneath the power module. For additional layout guide-lines, refer to FLTR100V20 data sheet.

Post Solder Cleaning and Drying Considerations
Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly. For guidance on appropriate soldering, cleaning and drying procedures, refer to Tyco Electronics Board Mounted Power Modules: Soldering and Cleaning Application Note (AP01-056EPS).
