The SIL20C2 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 SIL20C2 series offers

remote ON/OFF and over-current protection as standard.
