The SIL15 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 SIL15 series offers remote ON/OFF and

over-current protection as standard. With full international safety approval including

EN60950 and

UL/cUL60950, the SIL15 reduces compliance costs and time to market.
