SPECIFICATIONS

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.
