LTC3900 Datasheet (Linear Technology) - Synchronous Rectifier Driver

LTC3900, Synchronous Rectifier Driver

The LTC®3900 is a secondary-side synchronous rectifier driver designed to be used in isolated forward converter power supplies.

The chip drives N-channel rectifier MOSFETs and accepts pulse sychronization from the primary-side controller via a pulse transformer.

The LTC3900 incorporates a full range
