The SIL/SMT20C2 series is a new high density, open frame, non-isolated converter for space sensitive applications. This model has a wide input range (4.5-13.8 Vdc) and offers a wide 0.59-5.1 V output voltage range with 20 A load capability. An external resistor adjusts the output voltage from its pre-set value of 0.59 V to any value up to the 5 V maximum. Typical efficiencies for the models are 93% for the 12 V input version. The series offers remote ON/ OFF and over-current protection as standard.
All specifications are typical at nominal input, full load at 25 C, unless otherwise stated OUTPUT SPECIFICATIONS Output voltage Output setpoint accuracy Line regulation Load regulation Min/max load Overshoot Undershoot Ripple and noise 5 Hz to 20 MHz Transient response At turn-on At turn-off (See Note 1) (See Notes 1, 2) (See Note 5) 0.1% trim resistors Low line to high line Full load to min. load 0.59-5.1 V 1.0% 0.2% 0.5% 0 A/20 A 0.5% max. 100 mV max. 30 mV Vin = 5 V, Vout = 2.5 V 130 mV max. deviation 50 s recovery within regulation band Coplanarity GENERAL SPECIFICATIONS Efficiency Switching frequency Approvals and standards (pending) Material flammability Weight MTBF 12 V @ 40 C 100% load Bellcore 332

Output Voltage Adjustment of the SIL/SMT20C2 Series
The ultra-wide output voltage trim range offers major advantages to users who select the SIL/SMT20C2. 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 0.59-5.1 V. When the SIL/SMT20C2 converter leaves the factory, the ouput has been adjusted to the default voltage of 0.59 V.
