FAN6241M6X

Secondary Side Synchronous

Rectifier Controller for

Flyback Converters

Description

The FAN6241M6X is a secondary−side synchronous rectifier (SR)

controller for an isolated flyback converter operating in Discontinuous

Conduction Mode (DCM). The adaptive dead−time control algorithm

minimizes the body diode conduction of SR MOSFET while

guaranteeing stable and robust SR operation against noise and

disturbance caused by the circuit parasitic components. The 26 V rated

input voltage LDO and Low VDD Under−Voltage Lockout (UVLO)

voltage allow FAN6241M6X to be used for wide ranges of switched

mode power supply output voltage without additional circuit.
