Linear Technology LTC3901 Synchronous Driver Datasheet
The LTC3901 provides a secondary‑side synchronous rectifier driver for isolated push‑pull and full‑bridge power supplies. It drives two external N‑channel MOSFETs and synchronizes with the primary side via a transformer‑generated signal. The device includes programmable timeout, reverse‑current sensing, and undervoltage lockout to protect the MOSFETs.
Typical applications include 48 V isolated DC/DC converters, telecom power supplies, industrial control power supplies, and automotive or heavy‑equipment power systems. The datasheet details electrical characteristics, pin functions, timing diagrams, and recommended layout for the 16‑lead narrow SSOP package.
