Product Overview
LTC3900 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. It 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. It also shuts off the drivers if the supply voltage is too low. It is widely used in application such as 48V input isolated DC/DC converters, isolated telecom power supplies, high voltage distributed power step-down converters, industrial control system power supplies, automotive and heavy equipment etc.
- Programmable timeout protection

- Undervoltage lockout
- Operating temperature is -40°C to 125°C
- Package style is 8-NSOIC
