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%.
The SMT10E series provides non‑isolated, surface‑mount DC‑DC conversion for 3.3 V or 5 V input voltages, delivering selectable output voltages from 0.8 V to 3.63 V at a maximum of 10 A. Designed for high‑density board designs, the converters achieve efficiencies as high as 96 % and include features such as remote ON/OFF control and remote sense.
Typical applications include distributed power, workstations, optical networking, and wireless equipment. The series complies with UL/cUL, CSA, and EN60950 safety standards and is available in RoHS‑compliant packages.
