The SIL20C Series is a new high density open frame non-isolated converter for space-sensitive
applications. Each model has a wide input range (4.5 Vdc to 5.5 Vdc or 10.2 Vdc to 13.8 Vdc)
and offer a wide 0.9 Vdc to 3.3 Vdc/5 Vdc output voltage range with a 20 A load. An external
resistor adjusts the output voltage from its pre-set value of 0.9 Vdc to any value up to the
maximum allowed value for that model. Typical efficiencies are 87% for the 5 V input version
and 91% for the 12 V input version at full load conditions. The SIL20C series offers remote
ON/OFF and overcurrent 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 0.9 Vdc to 5.0 Vdc. When the SIL20C-
12SADJ series converter leaves the factory the output has been adjusted to
the default voltage of 0.9 V

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-HJ.

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 50 ºC.
See Application Note 131 for ripple current requirements.
These models have a wide trim output. 5 Vin has an output of
0.9 Vdc to 3.3 Vdc and 12 Vin has an output of 0.9 Vdc to 5 Vdc. 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-HP4J.
TSE RoHS 5/6 (non Pb-free) compliant versions may be available on
special request, please contact your local sales representative for
details.
NOTICE: Some models do not support all options. Please contact
