description the interpoint ? mhv series? of dc-dc converters offers a wide input voltage range of 16 to 50 volts and a choice of nine different output voltage configurations comprised of single, dual or triple outputs. the 3.3 volt single, 5 volt single and dual and the triple output models will withstand transients of up to 80 volts for up to 120 milliseconds while maintaining output voltages. the 12 volt single and dual outputs will withstand transients up to 75 volts and the 15 volt single and dual outputs will withstand up to 60 volts for 120 milliseconds. the mhv series operates at 15 watts of output power (10 watts for the 3.3 volt single output) over the military temperature range of -55c to +125c while maintaining low input and output noise. c onverter d esign mhv series dc-dc converters are switching regulators that use continuous flyback conversion topology with a clock frequency of approximately 600 khz. mhv series converters incorporate two pulse width modulators (pwm) with one pwm phase shifted 180 from the other to create a dual phase/phase-shifted operation. each of the pwms operates at approximately one-half (300 khz) of the clock frequency. this proprietary technology minimizes input ripple and improves efficiency. on singles the output ripple is reduced. cross regulation is eliminated on dual output models which are independently regulated and do not require load balancing or minimum loading. on triple output models, this design provides completely independent regulation with no cross regulation effect between the main and auxiliary outputs and no minimum loading is required on the main output. i nhibit f unction the converter is enabled when the inhibit terminal is left unconnected. when the inhibit terminal is pulled low (<0.8 v) the converter shuts down, typically drawing 8.4 ma at 28 v i n or 15 ma at 50 v i n . sinking current required is v i n / 3.3 k ohm. for more information see table 7 on page 7. s ync hronization f unction applying an external signal of 40% to 60% duty cycle and 490 to 710 khz for single and dual output models will synchronize the converter to your system requirements. for triple output models the external frequency range is 500 to 700 khz. free run clock frequency is approximately 600 khz. if not used, the sync terminal must be left unconnected. see table 7 on page 7 t rim single output converters feature a trim range of as low as 80% to as high as 110% of v o u t nominal, depending on the model. to trim up, connect a resistor from output common (pin 4) to trim (pin 3). to trim down, connect a resistor from the positive output (pin 5) to trim (pin 3). for more information see table 1, table 2 and figure 6 on page 4. s creening the converters are offered with standard screening, es screening, or fully compliant to 883 mil-prf-38534 class h screening. see table 13 on page 20 and table 14 on page 21. standard microcircuit drawin gs (smd) are available. see table 5 on page 6. features n o cross regulation on dual outputs ? operating temperature -55c to +125c ? input voltage range 16 to 50 volts ? t ransient protection 80 v for 120 ms - 12 v o u t single and dual to 75 volts - 15 v o u t single and dual to 60 volts ? fully isolated ? fixed frequency switching ? output trim on single output models ? inhibit and sync functions ? u ndervoltage lockout models o utput v oltage (v) si n gle d u al triple 3.3 5 +5 & 12 5 12 +5 & 15 12 15 15 m hv s ingle, d ual and t riple dc - dc c onverters page 1 of 21 mhv rev ac - 2015.01.23 crane aerospace & electronics power solutions crane aerospace & electronics power solutions - interpoint products 10301 willows road ne, redmond, wa, 98052 +1.425.882.3100 ? power@crane-eg.com www.craneae.com/interpoint 28 volt input C 15 watt
u nd ervoltage l ockout an undervoltage lockout of approximately 7 volts keeps system current levels low during startup. low line dropout typically occurs at approximately 12 v i n to 17 v i n depending on model. see figure 13 and figure 14 on page 13 and figure 23 on page 14. s hort c ircuit p rotection u nder short circuit conditions of 130% or more of full load current, the converter will protect itself by shutting down. short circuit duration should be brief because power dissipation may cause internal temperatures to rise rapidly. restart is automatic upon removal of the short circuit. 0 180 a ~ a ~ positive input pwm c on tro ll er pwm c on tro ll er sync in f eedback opto clock i nh ibit positive output out put common trim primary secondary common input f igure 1: mhv s ingle b lock d iagram page 2 of 21 mhv rev ac - 2015.01.23 m hv s ingle, d ual and t riple dc - dc c onverters crane aerospace & electronics power solutions www.craneae.com/interpoint 28 volt input C 15 watt
