OB2576ATCP Overview
Description
OB2576xT is an excellent primary side regulation power switch with CC/CV operation for medium level power AC/DC charger and adapter applications. The device integrates an internal power MOSFET and operates in QR mode to provide high efficiency along with several functions of built-in protections.
Key Features
- Primary-side sensing and regulation operates in QR mode without TL431 and opto-coupler
- High precision constant voltage and current regulation at universal AC input
- Programmable CV and CC regulation
- Integrated power MOSFET
- Good dynamic response
- Built-in line compensation for tight CC regulation
- Built-in fixed cable compensation
- Built-in primary winding inductance compensation
- Built-in control loop compensation
- Built-in leading edge blanking (LEB)
