USR3651 Datasheet (UTC) - HIGH PRECISION CC/CV PRIMARY-SIDE PWM POWER SWITCH

USR3651, HIGH PRECISION CC/CV PRIMARY-SIDE PWM POWER SWITCH

The UTC USR3651 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
