OB2571, OB2571-On, High Performance QR mode Primary-Side Power Switch

OB2571x High Performance QR mode Primary-Side Power Switch GENERAL .
OB2571x 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
* Integrated power MOSFET
* Good dynamic response
* Programmable Brownou

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. It removes the need for secondary feedback circuitry to lower the total bill of material cost. Proprietary Constant Voltage (CV) and Constant Curre
