The SMT15F-12 is a non-isolated DC-DC converter in the SMT series, packaged in a surface-mount footprint, providing designers with an economical solution for converting from a 12V source. The SMT15F-12 has an input range of 10.8Vdc to 13.2Vdc and offers an output voltage range from 1.0Vdc to 1.8Vdc with a 15A 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 1.8Vout.
The SMT15F‑12 series provides a compact, surface‑mount DC‑DC conversion solution for 12 V sources. It offers a single fixed output voltage selectable between 1.0 V and 1.8 V, a 15 A current rating, and up to 88 % efficiency, making it suitable for distributed power, workstations, optical networking and wireless applications.
Typical specifications include an input range of 10.8‑13.2 Vdc, total power of 15 W, a small 7 g weight, and operation from –40 °C to +85 °C. The device features an active‑high remote ON/OFF pin, optional remote‑sense, and a standard 6‑pin surface‑mount package with detailed mechanical drawings and pinout information.

The converter operates from 10.8 Vdc to 13.2 Vdc.
The output can be set between 1.0 Vdc and 1.8 Vdc.
It can supply up to 15 A of load current.
When the pin is pulled high the converter is ON; pulled low it is OFF. Leaving the pin open leaves the converter ON.
