HT7L5821 - Integrated PFC and Quasi-Resonant Current Mode PWM Controller

Download the HT7L5821 datasheet PDF. This datasheet also covers the HT7L5820 variant, as both devices belong to the same integrated pfc and quasi-resonant current mode pwm controller family and are provided as variant models within a single manufacturer datasheet.

Features

  • Integrated Transition Mode (TM) PFC controller and Quasi-Resonant (QR) flyback controller.
  • Wide AC input range from 85VAC to 265VAC.
  • Integrated 650V JFET quick high voltage start-up.
  • Integrated THD PFC stage optimiser.
  • Brown-out and brown-in protection.
  • Internal accurate feedback reference voltage: ±2%.
  • Internal 9.6ms PWM soft-start.
  • High/Low line over-power compensation.
  • FB pin protection (Auto Recovery).
