General Description

WS3252 is a high-integrated offline PWM controller, optemized for high poformance low power AC/DC charger and adapter adapter application.

WS3252 operates in primary-side sensing and regulation.

Consequently, opto-coupler and TL431 could be eliminated, thus reduce the cost.

Key Features

  • 5uA ultra-low startup current.
  • 2mA Low operating current.
  • ±5% Constant Voltage Regulation at Universal AC input.
  • Primary-side Sensing and Regulation Without TL431 and Opto-coupler.
  • Programmable CV and CC Regulation.
  • Built-in Primary winding inductance compensation.
  • Programmable cable drop compensation.
  • Built-in soft start.
  • Built-in Leading-edge blanking.
  • Cycle by cycle over current protection (OCP).
  • VCC over voltage clamp & under voltage loc.
