HIGH PRECISION CC/CV PRIMARY-SIDE PWM POWER SWITCH

The UTC US3651A is a primary control switch mode charger and adapter applications. The controlled variable is transferred by an auxiliary winding from the secondary to the primary side. The device integrates PWM controller to enhance the performance of discontinuous conduction mode (DCM) flyback con including Cycle-by-cycle \n·current limiting, V DD ?over voltage protection, V DD clamp, OTP, \n·leading edge blanking, V DD ?under voltage lockout, etc. \n?\n·??? FEATURES \n?\n· Built-in 650V Power MOSFET \n· (-5% ,+15%) constant voltage regulation at universal AC input\n· High precision c;
