HIGH PRECISION CC/CV PRIMARY SIDE SWITCHING REGULATOR

The UTC UPSRB04 is a primary control unit for switch modecharger and adapter applications. The controlled variable istransferred by an auxiliary winding from the secondary to theprimary side. The device uses Pulse Frequency Modulation (PFM)method to build discontinuous conduction mode (DCM) flybackp including Cycle-by-cyclecurrent limiting, output over voltage protection, VDD over voltageprotection, 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 Primary side c;
