UPSRB01B Datasheet (Unisonic Technologies) - HIGH PRECISION CC/CV PRIMARY SIDE SWITCHING REGULATOR

UPSRB01B, HIGH PRECISION CC/CV PRIMARY SIDE SWITCHING REGULATOR

The UTC UPSRB01B 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) fly
