Overview

iW1762 Product Brief Ultra-Low No-Load Power Digital Quasi-Resonant PWM Controller 1.

Key Features

  • Ultra-low no-load power consumption with lowest system cost (< 20mW at 230VAC in typical 20W and above power supplies).
  • Primary-side feedback eliminates opto-isolators and simplifies design.
  • Intelligent low power management achieves ultra-low operating current (~300μA) at no-load.
  • Adaptive load transient detection and fast response.
  • Adaptively controlled soft-start enables fast and smooth start-up for a wide range of capacitive loads (from 330μF.
