SIL12F Series
3.3 Vin to 5 Vin single output
DC-DC CONVERTERS F Class Non-isolated NEW Product 1 * Designed to meet ultra fast transient requirements up to 300 A/s step load transients * 12 A current rating * Input voltage range: 3.0 Vdc to 5.5 Vdc * Output voltage range: 0.9 Vdc to 3.3 Vdc * Extremely low internal power dissipation * Minimal thermal design concerns * RoHS compliant
The SIL12F series is a new range of ultra-compact non-isolated point-of-load converters for space-critical applications. The new SIL12F TyphoonTM family single-inline converter has a footprint of just 38.1 x 8.5 mm - and unlike competitive products on the market, requires only the addition of a small number of ceramic output capacitors to realise a complete high-performance point-of-load (POL) solution. The SIL12F is primarily intended for use on very densely packed, high functionality boards and for powering advanced silicon including network and communication processors, DSPs, FPGAs and ASICs. A key advantage of the SIL12F is that it only needs the addition of five 22 F ceramic output capacitors to provide a complete fullspecification, high efficiency POL solution with transient response capabilities that extend up to 300 A/s. The total board space required for the module and capacitors is a mere 400 mm2, facilitating easy co-location with the load. 2 YEAR WARRANTY All specifications are typical at nominal input, full load at 25 C unless otherwise stated.

The ultra-wide output voltage trim range offers major advantages to users who select the SIL12F-05W3V3-VJ. It is no longer necessary to purchase a variety of modules in order to cover different output voltages. The output voltage can be trimmed in a range of 0.9 Vdc to 3.3 Vdc. When the SIL12F-05W3V3-VJ converter leaves the factory the output has been adjusted to the default voltage of 3.3 V.
* When Vin 4.5 V, then Vout can be adjusted from 0.9 Vdc to 3.3 Vdc * When Vin < 4.5 V, then Vout can be adjusted from 0.9 Vdc to 2.5 Vdc
Notes
1 The SIL12F-05 features an `Active Low' Remote ON/OFF operation. If you are not using the Remote ON/OFF pin, leave the pin open (the converter will be on). The Remote ON/OFF pin is referenced to ground. The following conditions apply for the SIL12F-05: Configuration Remote pin open circuit Remote pin pulled low Remote pin pulled high Converter Operation Unit is ON Unit is ON Unit is OFF 5 6 7
Notes Cond.
3 4 A 22 F ceramic input capacitor may be required for test purposes only. See Application Note 181 for further details. An external output capacitor is required for basic operation. Required capacitance is a minimum of 110 F to meet the performance parameters. This can be made up of any combination of 22 F or 47 F multi-layer ceramic capacitors in 1210 case sizes. Ripple and Noise is worst case measurement. Typical value is 25 mV pkpk. TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special request, please contact your local sales representative for details. NOTICE: Some models do not support all options. Please contact your local Artesyn representative or use the on-line model number search tool at http://www.artesyn.com/powergroup/products.htm to find a suitable alternative.

An `Active High' Remote ON/OFF version is also possible with this converter. To order please place the suffix `R' towards the end of the part number, e.g. SIL12F-05W3V3-VRJ. See Figures 1, 2 and 3 for derating curves.

Pin No. Pin Description
1, 3, 5 2, 4 +Vout: The regulated positive power output with respect to the GND node. Ground: This is the common ground connection for the Vin and Vout power connections. It is also the 0 Vdc reference for the control inputs. V sense +: The sense input allows the regulation circuit to compensate for voltage drop between the module and the load. For optimal voltage accuracy Vo Sense should be connected to Vout node of bypass capacitor. It can also be left disconnected. V sense -: The VSense should be connected to the ground of a bypass capacitor near the load or left open circuit. Trim: A 1% 0.1 W resistor must be directly connected between this pin and pin 2 (GND) to set the output voltage to a lower value than 3.3 V. The temperature stability of the resistor should be 100 ppm/C or better. The set point range is from 3.3 V to 0.9 V. The resistor required for a given output voltage may be calculated from the following formula:
Pin No. Pin Description
If left open circuit the output voltage will default to 3.3 V. For further information on output voltage adjustment consult the Application Note 181. +Vin: The positive input voltage power node to the module,which is referenced to common GND. Power Good: This pin indicates the status of the output voltage. Power Good is driven low if output voltage deviates outside of specified limits. Margin+: When this input is asserted to High, the output voltage is increased by 5%. This function is independant of trim and sense. Margin-: When this input is asserted high, the output voltage is decreased by 5% from the nominal. This function is independant of trim and sense. Remote ON/OFF: Applying a high level signal to this input disables the module's output and turns off the output voltage. When the Remote ON/OFF control is active, the input current drawn by the regulator is significantly reduced. If the Remote ON/OFF pin is left open-circuit, the module will produce an output whenever a valid input source is applied.
