SIL15

SIL15 Series DC/DC CONVERTERS • • • • • • • • • • Single output 1 NEW Product 15A Non-Isolated DC/DC Converters Ultra-wide trim range (0.9V to 3.3V/5V) Current sink capable for termination applications Horizontal and vertical models available High power density design means reduced board space requirement Power good output signal (open collector) Operating ambient temperature up to +80ºC with suitable derating and forced air cooling Remote ON/OFF (active high) 0A minimum load Input undervoltage lockout Over-current and short-circuit protection The SIL15 Series is a new high density open frame non-isolated converter for spacesensitive 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. All specifications are typical at nominal input, full load at 25°C unless otherwise stated 2 YEAR WARRANTY SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage adjustability (See Note 5) 5V input models 12V input models 0.9V to 3.3V 0.9V to 5.0V ±2.5% ±0.2% max.
