PRIMARY-SIDE REGULATION PWM POWER SWITCH

The UTC USR1652 is a primary control switch mode chargerand adapter applications. The controlled variable is transferred byan auxiliary winding from the secondary to the primary side. Thedevice integrates PWM controller to enhance the performance ofdiscontinuous conduction mode (DCM) flyback convert including Cycle-by-cyclecurrent limiting, VDD over voltage protection, VDD clamp, OTP,leading edge blanking, VDD under voltage lockout, etc. FEATURES  Programmable CV and CC regulation Primary-side sensing and regulation with No TL431 and opto-coupler Multi-mode operation for high efficiency Adjusta;
