The SMT15F-12 series are non-isolated dc-dc converters packaged in a surface-mount footprint
giving designers a cost effective solution for conversion from a 12 V source. The SMT15F-12 has an
input range of 10.8 Vdc to 13.2 Vdc and offers an output voltage range from 1.0 Vdc to 1.8 Vdc with a
15 A load, which allows for maximum design flexibility and a pathway for future upgrades. The
SMT15F-12 is designed for applications that include distributed power, workstations, optical network
and wireless applications. Implemented using state of the art surface-mount technology and
automated manufacturing techniques, the SMT15F-12 offers compact size and efficiencies of up to
88% at 1.8 Vout.
