General Description

HT2269 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications.

PWM switching frequency at normal operation is frequency shuffling technique together with soft switching control at the totem pole gate drive output.

The tone energy at below 20KHZ is minimized in operation.

Key Features

  • Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power Design.
  • Audio Noise Free Operation.
  • External Programmable PWM Switching Frequency.
  • Internal Synchronized Slope Compensation.
  • Low VIN/VDD Startup Current(6.5uA) and Low Operating Current (2.3mA).
  • Leading Edge Blanking on Current Sense Input.
  • Complete Protection Coverage With Auto Self- Recovery.
  • External Programmable Over Temperature Protection (OTP).
  • On-chip VDD OVP for Sy.
