UC1100 Datasheet (Unisonic Technologies) - LOW-POWER HIGH PRECISION CC/CV PRIMARY SIDE SWITCHING REGULATOR

UC1100, LOW-POWER HIGH PRECISION CC/CV PRIMARY SIDE SWITCHING REGULATOR

The UTC UC1100 is a primary control unit for switch mode charger and adapter applications.

The controlled variable is transferred by an auxiliary winding from the secondary to the primary side.

The device uses Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyba
