FAN6240M6X Datasheet Secondary-side Synchronous Rectifier Controller

Manufacturer: Fairchild (now onsemi)

Overview: FAN6240 — Secondary-Side Synchronous Rectifier Controller for Flyback Converters July 2016 FAN6240 Secondary-Side Synchronous Rectifier Controller for Flyback.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

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.

30 V rated input voltage LDO and Low VDD UnderVoltage Lockout (UVLO) voltage allow FAN6240M6X to be used for wide ranges of switched mode power supply output voltage without additional circuit.

Key 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.
