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 3.3 Vdc or 5 Vdc input to output voltages
of 0.8 Vdc and 3.63 Vdc. The SMT15E offers a range of fixed outputs (and one wide trim output unit) at
an industry leading 15 A which allows maximum design flexibility and a pathway for future upgrades.
Local voltage conversion by the SMT15E series from existing 3.3 Vdc or 5 Vdc 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 96%.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated
