◆    Supports both High-side and Low-side rectification

◆   No need external power supply

APPLICATIONS

◆   Adapters/Chargers

◆   Flyback converters

GENERAL DESCRIPTION

SF7707X is a high performance secondary side switch for synchronous rectification (SR) in DCM operation flyback.

Using SF7707X to replace diode can effectively reduce the secondary side rectifier power dissipation and increase efficiency for system.

SF7707X is offered in SOP8 package.
