Product Description
EUP9291-Synchronous Rectifier Controller
Description
The EUP9291 is a high performance controller used to secondary side synchronous rectifier (SR).
The fundamental of EUP9291 is utilized N-channel MOSFET power devices used for secondary side synchronous to emulate a near-ideal diode rectifier. This method not only directly reduces power dissipation of the rectifier but also reduces primary side losses as well.
The EUP9291 is applied voltage-second balancing control method and not directly connected to the MOSFET drain, so it is ideal for flyback power supplies over the wide-output voltage range. The SR drive turn-off threshold is not related to the MOSFET RDS(on), which allows optimizing for maximum conduction time.
It is compatible with DCM, TM and CCM operation
