iW1780

iW1780 Rapid Charge AC/DC Digital Quasi-Resonant PWM Controller 1.0 Features 2.0 Description ●● Supports rapid charge technologies such as Qualcomm® Quick Charge™ 2.0 (QC2.0) technology to provide 5V/9V/12V with user-selected various output current limit combinations ●● Proprietary secondary-to-primary digital communication and built-in decoder eliminate discrete decoder and significantly simplify system design ●● Single opto-coupler for all the rapid charge information: output voltage request, output current limit, output voltage undershoot, and over-voltage protection ●● Tight multi-level constant-voltage and multi-level constant-current regulation with primary-side feedback and control ●● Ultra-low no-load power consumption with lowest system cost (< 10mW at 230VAC with typical 5V2A setting using Schottky diode rectifer; < 20mW at 230VAC with typical 5V2A setting using synchronous rectifier) ●● Fast dynamic load response (DLR) with secondary-side load ...
