    SF7201 is a secondary-side Synchronous Rectification (SR) power switch. It built in a 50V ultra low on state resistance(typical 15mΩ,VDD=5V) SR MOSFET for improving efficiency in Discontinuous Conduction Mode(DCM) and Quasi-Resonant(QR) flyback converters

     SF7201 integrates functions and protections of Under Voltage Lockout(UVLO),VDD Clamper ,etc.

     SF7201 is available in SOP-8 package.
