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.
