The SIL20C Series is a new high density open frame non-isolated converter for space-sensitive
applications. Each model has a wide input range (4.5 Vdc to 5.5 Vdc or 10.2 Vdc to 13.8 Vdc)
and offer a wide 0.9 Vdc to 3.3 Vdc/5 Vdc output voltage range with a 20 A load. An external
resistor adjusts the output voltage from its pre-set value of 0.9 Vdc to any value up to the
maximum allowed value for that model. Typical efficiencies are 87% for the 5 V input version
and 91% for the 12 V input version at full load conditions. The SIL20C series offers remote
ON/OFF and overcurrent protection as standard. With full international safety approval including
EN60950 and
UL/cUL60950
, the SIL20C reduces compliance costs and time to market.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated
