Description
OB2576x High Performance QR mode controller GENERAL .
OB2576x is an excellent primary side regulation controller with CC/CV operation for medium level power AC/DC charger and adapter applications.
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
* Good dynamic response
* Built-in line compensation for tight CC
regulation
Applications
* The device operates in QR mode to provide high efficiency along with several functions of built-in protections. It removes the need for secondary feedback circuitry to lower the total bill of material cost. Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrated as shown i
