SIL25C

SIL25C Series DC-DC CONVERTERS • • • • • • C Class Non-isolated 12 Vin single negative output 1 NEW Product • • 25 A current rating Input voltage range: 10.2 Vdc to 13.8 Vdc nominal output voltage: -5.05 Vdc Industry leading value • Cost optimized design Excellent transient response Output Voltage adjustability • Supports silicon voltage migration • Resulting in reduced design-in and qualification time Designed in reliability: MTBF of 3 million hours per Telcordia SR-332 Available RoHS compliant The SIL25C Series is a new high density non-isolated dc-dc converter. The converter has a wide input range (10.2 Vdc to 13.8 Vdc) and offers a -4.5 Vdc to -5.5 Vdc output voltage range with a 25 A load. The series offers remote ON/OFF, overtemperature protection and overcurrent protection as standard. The remote sense feature enables the SIL25C compensate for voltage drops between the converters output and the load. With full international safety approvals including EN60950 and UL/cUL60950 the SIL25C reduces compliance costs and time to market. 2 YEAR WARRANTY All specifications are typical at nominal input, full load at 25 °C ambient unless otherwise stated SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage adjustability (See Note 1) -4.5 Vdc to -5.5 Vdc ±3.0% ±1.0% max. ±1.0% max. 0 A/25 A (See Note 2) Deviation 100 mV pk-pk 50 mV rms 75 mV typ. 150 µs recovery to within regulation band INPUT SPECIFICATIONS (CONTD.)
