UPSR104 Datasheet High Precision Cc/cv Primary-side Pwm Controller

Manufacturer: Unisonic Technologies

Overview: UNISONIC TECHNOLOGIES CO., LTD UPSR104 Preliminary HIGH PRECISION CC/CV PRIMARY-SIDE PWM CONTROLLER.

General Description

The UTC UPSR104 is a primary controller 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 converters.
