Description

This highly integrated PWM controller provides several

Features

  • Linearly decreasing PWM frequency.
  • Green-mode under light-load and zero-load conditions.
  • Constant voltage (CV) and constant current (CC).
  • No secondary feedback.
  • Low start-up current (8µA).
  • Low operating current (3.6mA).
  • Leading-edge blanking.
  • Constant power limit.
  • Universal AC input range.
  • Synchronized slope compensation.
  • 140°C OTP sensor with hysteresis.
  • VDD over-voltage clamping.
