OB2576xT
High Performance QR mode Primary-Side Power Switch
GENERAL 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. 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 in the figure below. In CV control, the controller changes the mode of operation according to load condition. At full loading, the...
