12-65W Green-mode Flyback Power Supply Controller

12-65W Green-mode Flyback Power Supply Controller - UCC28610
Datasheet
 

Description

The UCC28610 brings a new level of performance and reliability to the AC and DC consumer power supply solution.

A PWM modulation algorithm varies both the switching frequency and primary current while maintaining discontinuous or transition mode operation over the entire operating range. Combined with a cascoded architecture, these innovations result in efficiency, reliability, and system cost improvements over a conventional flyback architecture.

The UCC28610 offers a predictable maximum power threshold and a timed response to an overload, allowing safe handling of surge power requirements. Overload fault response is user-programmed for retry or latch-off mode. Additional protection features include output overvoltage detection, programmable maximum on-time, and thermal shutdown.

Features

  • Cascoded Configuration Allows Fully Integrated
    Current Control Without External Sense Resistor
  • Fast Start Up With Low Standby Power Achieved
    by Cascode Configuration
  • Frequency and Peak Current Modulation for
    Optimum Efficiency Over Entire Operating Range
  • Green-Mode (GM) Burst Switching Packets
    Improve No-Load Efficiency
  • Advanced Overcurrent Protection Limits RMS
    Input and Output Currents
  • Thermal Shutdown
  • Timed Overload With Retry or Latch-Off
    Response
