Rapid Charge AC/DC Digital Quasi-Resonant PWM Controller
1.0 Features
2.0 Description
- - Supports rapid charge technologies such as Qualm® Quick Charge™ 2.0 (QC2.0) technology to provide 5V/9V/12V with user-selected various output current limit binations
- - Proprietary secondary-to-primary digital munication 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 (< 10m W at 230VAC with typical 5V2A setting using Schottky diode rectifer; < 20m W at 230VAC with typical 5V2A setting using synchronous rectifier)
- - Fast dynamic load response (DLR) with secondary-side...
