Artesyn SMT10E User Manual

The SMT10E 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 SMT10E offers a
range of fixed outputs (and one wide trim output unit) at an
industry leading 10 A which allows maximum design flexibility and
a pathway for future upgrades. Local voltage conversion by the
SMT10E series from existing 3.3Vdc or 5 Vdc system voltages
eliminates the need for redesign of existing power architectures
when voltage requirements change. The SMT10E 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 SMT10E offers compact size and efficiencies of up
to 96%.
