SMT15C Series 5 Vin and 12 Vin single output DC-DC CONVERTERS • • • • • • • • C Class Non-isolated 1 NEW Product 15 A current rating Input voltage range: 4.5 Vdc to 5.5 Vdc or 10.2 Vdc to 13.8 Vdc Output voltage range: 0.9 Vdc - 3.3/5.0 Vdc Industry leading value • Cost optimized design Excellent transient response Output voltage adjustability • Pathway for future upgrades • Supports silicon voltage migration • Resulting in reduced design-in and qualification time Designed in reliability: MTBF of >7 million hours per Telcordia SR-332 Available RoHS compliant 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 13.8 Vdc) 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. 2 YEAR WARRANTY All specifications are typical at nominal input Vin = 12 V, full load at 25 °C unless otherwise stated INPUT SPECIFICATIONS (CONTD.)

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.
