The SMT15E series are non-isolated DC/DC converters packaged in a surface mount footprint
giving designers a cost effective solution for conversion from either a 3.3V or 5V input to output
voltages of 3.3V and 2.5V. The SMT15E offers a range of fixed outputs at an industry leading
15A which allows maximum design flexibility and a pathway for future upgrades. Local voltage
conversion by the SMT15E series from existing 3.3V or 5V system voltages eliminates the need
for redesign of existing power architectures when voltage requirements change. The SMT15E 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 SMT15E offers compact size and efficiencies of up to
95%.

Notes
1Referenced to ground for shutdown. If pin 1 is high unit will shutdown.
If pin 1 is open unit will operate as normal. Converter is guaranteed OFF
when pin 1 is greater than 1.2V.
2For 3.3Vout, the input must be greater than 4.5V
3For 2.5Vout, the input must be greater than 3.3V
4Full de-rating curves available in both the Long Form Data Sheet and
