UPSR100 HIGH PRECISION CC/CV PRIMARY SIDE REGULATOR

The UTC UPSR100 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) flyb.
