NEW Product

The SMT10E 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 SMT10E has a

wide input range (10 Vdc to 14 Vdc) and offers a wide 0.8 Vdc to 3.63 Vdc output voltage range

with a 10 A load, which allows for maximum design flexibility and a pathway for future upgrades.

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 94%.
