The SMT15C 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 13.8Vdc) and offers
a wide 0.9 Vdc to 5.0 Vdc output voltage range with a 15 A load.
An external resistor adjusts the output voltage from its pre-set
value of 0.9 V to any value up to the 5 V maximum. Typical
efficiencies for the models are 89% for the 5 V input version and
91% for the 12 V input version. The series offers remote ON/OFF
and overcurrent protection as standard. With full international
safety approvals including EN60950 and UL/cUL60950, the
SMT15C reduces compliance costs and time to market.

Output Voltage Adjustment of the SMT15C Series
The ultra-wide output voltage trim range offers major advantages to users who
select the SMT15C 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 SMT15C series converter
leaves the factory the output has been adjusted to the default voltage of 0.9 V.
