The SIL20C 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 20A 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 87% for the 5V input version and 91% for the 12V input
version at full load conditions. The SIL20C series offers remote ON/OFF and over-current
protection as standard. With full international safety approval including EN60950 and
UL/cUL60950
, the SIL20C reduces compliance costs and time to market.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated

Output Voltage Adjustment of the SIL20C-12SADJ Series
The ultra-wide output voltage trim range offers major advantages to users who
select the SIL20C-12SADJ series. It is no longer necessary to purchase a
variety of modules in order to cover different output voltages. The output
voltage can be trimmed in a range of 0.9V to 5.0V. When the SIL20C-12SADJ
series converter leaves the factory the output has been adjusted to the default
voltage of 0.9V

Measured with external filter. See Application Note 131 for details.
Uses external resistor from trim pin to output ground. Min value =
485Ω for 5V model, 280Ω for 12V model. See Application Note 131
for details.

This product is only for inclusion by professional installers within
other equipment and must not be operated as a stand alone
product.
The standard unit with the suffix '-V' is for vertical mounting. To
order a unit with horizontal mounting, please add the suffix '-H' to
the model number, e.g. SIL20C-05SADJ-H.
Power-up is the time from application of DC input to Power Good
enabled. Remote ON/OFF is from ON/OFF asserted high to power
good enabled.
See Application Note 131 for operation above 50ºC.
See Application Note 131 for ripple current requirements.
These models have a wide trim output. 5Vin has an output of 0.9V to
3.3V and 12 Vin has an output of 0.9V to 5V. An external resistor
adjusts the output voltage.
To order a unit with a pin length of 0.150”, please add suffix ‘P4’ to
the model number, e.g. SIL20C-05SADJ-HP4.
