iW1767 - Ultra-Low No-Load Power Digital Quasi-Resonant PWM Controller
Features
Ultra-low no-load power consumption with lowest system cost (< 20mW at 230VAC in typical 12V2A power supplies).
Fast dynamic response with secondary-side load transient detection.
Adaptively controlled soft-start enables fast and smooth start-up for a wide range of capacitive loads (from 330μF to 6,000μF) with output voltage up to 12V.
Tight constant-voltage and constant-current regulation across line and load range with primary-side feedback and control.
