Description
General part information
UCC24630 Series
The UCC24630 SR controller is a high-performance controller and driver for N-channel MOSFET power devices used for secondary-side synchronous rectification.
The combination of controller and MOSFET emulates a near-ideal diode rectifier. This solution not only directly reduces power dissipation of the rectifier but also reduces primary-side losses as well, due to compounding of efficiency gains.
Utilizing a volt-second balancing control method, the UCC24630 is ideal for flyback power supplies over a wide-output voltage range since the device is not connected directly to the MOSFET drain. The SR drive turn-off threshold is not dependent on the MOSFET RDS(on)which allows optimizing for maximum conduction time. Also secondary current ringing due to device and layout inductance does not affect the SR turn-off threshold.
