The SMT30E series are non-isolated DC/DC converters packaged in a surface-mount footprint
giving designers a cost effective solution for conversion from a 12V source. The SMT30E has a
wide input range (8V to 14V) and offers a wide 0.8 to 3.63V output voltage range with a 30A load,
which allows for maximum design flexibility and a pathway for future upgrades. The SMT30E 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 SMT130E offers compact size and efficiencies of up to
91%.
