UCC24636 - Synchronous Rectifier Controller

General Description

The UCC24636 SR is a compact, 6-pin secondaryside synchronous rectifier MOSFET controller and driver for high efficiency Flyback converters operating in Discontinuous (DCM) and Transition mode (TM).

Key Features

  • 1 Secondary-Side SR Controller Optimized for 5-V to 24-V Output Discontinuous/Transition Mode Only Flyback Converters.
  • Volt-Second Balance Control Enables Highest Rectifier Efficiency.
  • Compatible with PSR and SSR Flyback Controllers.
  • Ultra Low 110-µA Standby Current Consumption.
  • Auto-Detect Standby Mode Disables SR Switching for Lower No-Load Power Consumption.
  • SR Turn-Off Independent of RDSON and Parasitic Inductance.
  • Operating Freq.
