The SMT15C series is a new high density open-frame, non-isolated converter for space sensitive applications. Each model has a wide input range (4.5 Vdc to 5.5 Vdc or 10.2 Vdc to 13.8Vdc) and offers a wide 0.9 Vdc to 5.0 Vdc output voltage range with a 15 A load. An external resistor adjusts the output voltage from its pre-set value of 0.9 V to any value up to the 5 V maximum. Typical efficiencies for the models are 89% for the 5 V input version and 91% for the 12 V input version. The series offers remote ON/OFF and overcurrent protection as standard. With full international safety approvals including EN60950 and UL/cUL60950, the SMT15C reduces compliance costs and time to market.
The SMT15C Series is a high‑density, open‑frame, non‑isolated power converter designed for space‑sensitive applications. It offers a wide input range (4.5‑5.5 Vdc or 10.2‑13.8 Vdc) and an adjustable output voltage from 0.9 Vdc up to 5.0 Vdc, with a continuous 15 A current rating.
The series includes remote ON/OFF control, over‑current protection, and complies with international safety standards such as EN60950 and UL/cUL60950. Typical efficiencies are 89 % (5 V input) and 91 % (12 V input), with a fixed 200 kHz switching frequency and an MTBF of over 7 million hours.
