The SIL15C Series is a new high density open frame non-isolated converter for space-
sensitive applications. Each model has a wide input range (4.5 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 15 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 89% for the 5 V
input version and 91% for the 12 V input version. The SIL15C series offers remote ON/OFF
and overcurrent protection as standard. With full international safety approval including
EN60950 and
UL/cUL60950
, the SIL15C reduces compliance costs and time to market.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated
