SIL30C Series | 30A DC/DC Converter
C Class Non-Isolated
SIL30C SERIES
Single output
Wide trim range (0.9V to 5.0V)
Horizontal and vertical models available
High power density design means reduced board space requirement
Remote sense
Power good output signal (open collector)
Operating ambient temperature to 80ºC with suitable de-rating and forced air cooling
Remote ON/OFF (active high)
Over-temperature protection
0A minimum load
Input undervoltage lockout
Over-current and short-circuit protection
Current sharing option
The SIL30C is a new high density open-
frame non-isolated converter series for
space sensitive applications. The
converter has a wide input range (10.2 to
13.8Vdc) and offers a wide 0.9 to 5V
output voltage range with a 30A load. An
external resistor adjusts the output voltage
from its preset value of 0.9V to any value
up to the 5V maximum. The SIL has a
typical efficiency of 91%. The series
offers remote ON/OFF, over-temperature
protection and over-current protection as
standard.
Its current share facility supports parallel
operation of multiple SIL30C units and the
remote sense feature enables the SIL30C
compensate for voltage drops between
the converters output and the load. With
full international safety approvals including
EN60950 and UL/cUL60950 the SIL30C
reduces compliance costs and time to
market.
