Product Overview

The LTC3900ES8#PBF 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 synchronization from the primary-side controller via a pulse transformer. The LTC3900 incorporates a full range of protection for the external MOSFETs. A programmable timeout function is included that disables both drivers when the synchronization signal is missing or incorrect. Additionally, the chip senses the output inductor current through the drain-source resistance of the catch MOSFET, shutting off the MOSFET if the inductor current reverses. The LTC3900 also shuts OFF the drivers if the supply voltage is too low.
  • Programmable timeout protection
  • Reverse inductor current protection
  • Pulse transformer synchronization
  • Under-voltage lockout
