iW1679-50 Datasheet Off-Line Digital Green-Mode Quasi-Resonant PWM Controller

Manufacturer: Dialog Semiconductor (now Renesas)

Overview

iW1679-50 Off-Line Digital Green-Mode Quasi-Resonant PWM Controller 1.

Key Features

  • Optimized for 5V2A AC/DC adapters/chargers with < 30mW no-load power consumption at 230VAC and fast dynamic load response for both one-time and repetitive load transients.
  • Direct drive of low-cost BJT power switch.
  • Very tight constant voltage and constant current regulation over entire operating range.
  • PrimAccurateTM primary-side feedback eliminates opto-isolators and simplifies design.
  • EZ-EMI® design enhances manufacturability.
  • Intrin.
