The SIL15C Series is a new high density open frame non-isolated converter for space-
sensitive applications. Each model has a wide input range (4.5V to 5.5V or 10.2V to
13.8V) and offer a wide 0.9V to 3.3V/5V output voltage range with a 15A load. An external
resistor adjusts the output voltage from its pre-set value of 0.9V to any value up to the
maximum allowed value for that model. Typical efficiencies are 89% for the 5V input
version and 91% for the 12V input version. The SIL15C series offers remote ON/OFF and
over-current protection as standard. With full international safety approval including
EN60950 and
UL/cUL60950
, the SIL15C reduces compliance costs and time to market.
