Description
FAN6240 * Secondary-Side Synchronous Rectifier Controller for Flyback Converters July 2016 FAN6240 Secondary-Side Synchronous Rectifier Cont.
The FAN6240M6X is a secondary-side synchronous rectifier (SR) controller for an isolated flyback converter operating in Discontinuous Conduction Mode.
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
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
