The SIL/SMT20C2 series is a new high density, open frame, non-isolated
converter for space sensitive applications. This model has a wide input range
(4.5-13.8 Vdc) and offers a wide 0.59-5.1 V output voltage range with 20 A
load capability. An external resistor adjusts the output voltage from its pre-set
value of 0.59 V to any value up to the 5 V maximum. Typical efficiencies for
the models are 93% for the 12 V input version. The series offers remote ON/
OFF and over-current protection as standard.
All specifications are typical at nominal input, full load at 25 °C, unless otherwise stated

Output Voltage Adjustment of the SIL/SMT20C2 Ser
ies
The ultra-wide output voltage trim range offers major advantages to users
who select the SIL/SMT20C2. 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 0.59-5.1 V. When the SIL/SMT20C2 converter
leaves the factory, the ouput has been adjusted to the default voltage of 0.59 V.

Measured as per recommended system capacitance.
di/dt = 10 A/μs, Vin = Nom, Tc = 25 °C, load change = 0.75 lo to
full lo and full lo to 0.75.
External input fusing is recommended.
Additional part numbers may be available with different output
voltages.
Airflow dependent, 100 LFM minimum required.
No capacitor needed for ripple current capability.
No capacitor needed for stability.
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 may not support all options. Please
