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 12 V source. The SMT30E has a wide input
range (8 Vdc to 14 Vdc) and offers a wide 0.8 Vdc to 3.63 Vdc output voltage range with a 30 A 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 SMT30E offers compact size and efficiencies of up to 91%.
