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
