Overview
MX1118AS-LV is high performance offline PSR power switch for low power AC/DC charger and adapter applications. It operates in primary side sensing and regulation. Consequently, opto-coupler and TL431 could be eliminated. Proprietary constant voltage and constant current control is integrated. In CC control, the current and output power setting can be adjusted externally by the sense resistor Rcs at CS pin. In CV control, multimode operations are utilized to achieve high performance and high efficiency. In addition, good load regulation is achieved by the built in cable drop compensation. Device operates in PFM in CC mode at large load condition and it operates in PWM with frequency reduction at light/medium load. The chip consumes very low operation current. It achieves less than 75mW standby power to meet strict standby power standard. MX1118AS-LV offers comprehensive protection coverage with auto-retry feature including cycle-by-cycle current limiting, VDD over voltage protection, feedback loop open protection, short circuit protection, built-in leading edge blanking, VDD under voltage lockout and OTP etc. MX1118AS-LV is offered in SOP-8 package.
