HIGH PRECISION CC/CV? PRIMARY SIDE SWITCH

The UTC? USRB01 is a primary controller for 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) flyback power supp including Cycle-by-cycle current limiting, output over voltage protection, VDD over voltage protection, feedback loop open protection, short circuit protection, leading edge blanking, OTP, VDD under voltage lockout, etc. ???FEATURES ? ±5% constant voltage regulation at universal AC input Primar;
