The SIL40C2 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 0.6-5 V output voltage range with 40 A load capability.

An external resistor adjusts the output voltage from its pre-set value of 0.6 V to

any value up to the 5 V maximum. Typical efficiencies for the models are 91%

for the 12 V input version. The SIL40C2 series offers remote ON/OFF and

over-current protection as standard.
