High Performance QR mode controller
GENERAL DESCRIPTION
OB2576x is an excellent primary side regulation controller with CC/CV operation for medium level power AC/DC charger and adapter 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 in the figure below. In CV control, the controller changes the mode of operation according to load condition. At full loading, the controller operates in quasi-resonant (QR) mode in the...
