FAN6240M6X - Fairchild Semiconductor

FAN6240M6X Secondary-Side Synchronous Rectifier Controller

The FAN6240M6X 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. .

Features

 Works in Discontinuous Conduction Mode (DCM).
 Adaptive Turn-off Trigger Blanking Time for easier use
 Turn-on Trigger Blanking Time (Minimum-OFF Time) for Improved Noise Immunity
 Supports High-Frequency Applications up to 200 kHz
 Minimum Turn-on Delay (20 ns)
 Adaptive Turn-off Threshold Control for Minimized SR MOSFET Body Diode Conduction (Dead-Time is independent of SR MOSFET)
 Wide Voltage Range for LDO Input up to 30 V
 Small Footprint: SOT-23 6 Pin Package Description The FAN6240M6X is a secondary-side synchronous rectifier (SR) controller for an isolated flyback converter o.
