LT8309 Secondary-Side Rectifier Drivers

Analog Devices Inc. LT8309 Secondary-Side Synchronous Rectifier Drivers replace the output rectifier diode in a flyback topology. Applications are no longer restricted by the heat constraints of the output diode when the diode is replaced with an N-channel MOSFET. The IC replicates the behavior of a diode by sensing the drain-to-source voltage to determine when the current becomes negative. The components' low minimum on- and off-times help improve noise immunity.
