SIL25C-12SNEG-VJ pdf
SIL25C Series
12 Vin single negative output
DC-DC CONVERTERS C Class Non-isolated
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.
All specifications are typical at nominal input, full load at 25 °C ambient unless otherwise stated
