UCC28600 PWM Controller

Texas Instruments' 8-pin quasi resonant flyback green mode controller

image of Texas Instruments' UCC28600 PWM ControllerTexas Instruments' UCC28600 is a PWM controller with advanced energy features to meet stringent world-wide energy efficiency requirements. UCC28600 integrates built-in advanced energy saving features with high level protection features to provide cost effective solutions for energy efficient power supplies. UCC28600 incorporates frequency fold back and green mode operation to reduce the operation frequency at light load and no load operations.

UCC28600 is offered in the 8-pin SOIC (D) package. Operating junction temperature range is -40°C to 105°C. The Design Calculator, (Texas Instruments Literature number SLVC104), located in the Tools and Software section of the UCC28600 product folder, provides a user-interactive iterative process for selecting recommended component values for an optimal design.

Features
  • Green-mode controller with advanced energy saving features
  • Quasi-resonant mode operation for reduced EMI and low switching losses (low voltage switching)
  • Low standby current for system no-load power consumption
  • Low startup current: 25 µA maximum
  • Programmable overvoltage protection, line and load
  • Internal overtemperature protection
    • Current limit protection
    • Cycle-by-cycle power limit
  • Primary-side overcurrent hiccup restart mode
  • 1 A sink TrueDrive, -0.75 A source gate drive output
  • Programmable soft-start
  • Green-mode status pin (PFC disable function)

Applications

  • Bias supplies for LCD-monitors, LCD-TV, PDP-TV, and set top boxes
  • AC/DC adapters and offline battery chargers
  • Energy efficient power supplies up to 200 W
