CX7508 Overview
Description
CX7508 is a high performance offline PWM power switch for low power AC/DC charger and adapter operates in primary-side sensing and , opto-coupler and TL431 could be eliminated. High Precision Constant Voltage (CV) and Constant Current (CC) control are integrated as shown in the figure below.
Key Features
- ± 5% Constant Voltage Regulation and Current Regulation at Universal AC Input
- Primary Side Regulation (PSR) Without TL431 and Opto-coupler
- No Need for Control Loop Compensation
- Programmable CV and CC Regulation
- Multi-Mode PWM/PFM Operation
