OB2576CMP 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.
OB2576CMP Key Features
- Primary-side sensing and regulation operates in QR mode without TL431 and opto-coupler
