Abstract:
A synchronous rectifier (SR) controller includes a controller having an input adapted to be coupled to a drain of an SR transistor, and an output for providing a drive signal in response thereto, a gate driver having an input coupled to the output of the controller, and an output adapted to be coupled to a gate of the SR transistor for providing a gate signal thereto, a first transistor having a drain coupled to the gate terminal, a gate, and a source coupled to ground, and a protection circuit having an input coupled to the drain terminal, and an output coupled to the gate of the first transistor. The protection circuit is responsive to a voltage on the drain terminal exceeding a first voltage to provide a voltage on the gate of the first transistor greater than a turn-on voltage and less than an overvoltage of the first transistor.

Claim (Index 3):
The synchronous rectifier controller of  claim 1 , wherein said protection circuit comprises:\n a second transistor having a drain coupled to said drain terminal, a gate, and a source coupled to said gate of said first transistor; a first zener diode having a cathode coupled to said source of said second transistor, and an anode coupled to ground; and a bias circuit having a first terminal coupled to said drain terminal, a second terminal coupled to said gate of said second transistor, and a third terminal coupled to ground, wherein said bias circuit biases said gate of said second transistor to a voltage greater than a breakdown voltage of said first zener diode plus a threshold voltage of said second transistor in response to said voltage on said drain terminal.
