Secondary-Side Synchronous Rectifier Controller for Flyback Converters

Key Features

• Charge pump on gate output

• Gate zero clamp even though IC is inactivated

• Green mode at light load

• 120V rating of DRAIN pin

• Small footprint: SOT-23 6 pin package

• Adaptive turn-off trigger blanking time for easy use, the same as FAN6420

• Support high-frequency applications up to 200kHz with Discontinuous Conduction Modes (DCM) and BoundaryConduction Mode (BCM), the same as FAN6420

• Short turn-on time

Description

The FAN6241M6X is a secondary−side synchronous rectifier (SR)controller for an isolated flyback converter operating in DiscontinuousConduction Mode (DCM).
