The SMT05E 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 SMT05E 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 5A load, which allows for maximum design flexibility and a pathway for future upgrades. The SMT05E 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 SMT05E offers compact size and efficiencies of up to 91%.
The SMTO5E‑12W3V3 is a compact, non‑isolated DC‑DC converter designed for board‑space‑critical applications such as distributed power, workstations, optical networks and wireless systems. It accepts a wide input range of 10‑14 Vdc and provides an adjustable output from 0.8 Vdc to 3.63 Vdc at up to 5 A, achieving up to 91 % efficiency.
Typical specifications include a fixed 330 kHz switching frequency, 16.5 W total power, MTBF of 6,920,000 hours, and operation from –40 °C to +100 °C. The device meets UL/cUL 60950, CSA 22.2, and TUV EN60950 safety standards and is RoHS compliant.

It accepts an input voltage from 10 Vdc to 14 Vdc.
The converter reaches up to 91 % efficiency at 12 Vin and 3.3 Vout.
With positive‑logic remote control, leaving the pin open keeps the converter on; pulling it low turns it off, and pulling it high turns it on.
The output can be trimmed from 0.8 Vdc to 3.63 Vdc.
