FEATURES
2.0DESCRIPTION
●● 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
