Description	Off-Line Digital Green-Mode Quasi-Resonant PWM Controller

iW1679-50 Off-Line Digital Green-Mode Quasi-Resonant PWM Controller 1.0.

Optimized for 5V2A AC/DC adapters/chargers with < 30mW no-load power consumption at 230VAC and fast dynamic load respons
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
Intrinsically low mon mode noise
Optimized 72kHz maximum PWM switching frequency achieves best size and efficiency
Adaptive multi-mode PWM/PFM control improves efficiency
Quasi-resonant operation for highest overall efficiency
Dynamic base current control
