MX1118AS Datasheet | MAXINMICRO

FEATURES MX1118AS is high performance offline PSR power switch - Primary side sensing and regulation without PC817 for low power AC/DC charger and adapter applications. It and TL431 operates in primary side sensing and regulation. - High precision CC and CV at universal AC input Consequently, opto-coupler and TL431 could be eliminated. - Multimode operation for efficiency improving Proprietary constant voltage and constant current control is - 5A650V NMOSFET is integrated integrated as shown in the figure below. - Programmable CC and CV regulation In CC control, the current and output power setting can be - Built-in primary winding inductance pensation adjusted externally by the sense resistor Rcs at CS pin. In - Programmable cable drop pensation CV control, multimode operations are utilized to achieve - No need for control loop pensation high performance and high efficiency. In addition, good load - Audio noise free operation regulation is achieved by the built in cable drop - Ultra-low start up current and low operating current pensation. Device operates in PFM in CC mode at large - Built in leading edge blanking (LEB) load condition and it operates in PWM with frequency - prehensive protection coverage with auto-retry reduction at light/medium load. The chip consumes very low - VDD Under Voltage Lockout with hysteresis (UVLO) operation current. It achieves less than 75m W standby power - VDD Over Voltage Protection (VDD OVP) to meet strict standby power standard.MX1118AS offers - Cycle-by-cycle over current protection prehensive protection coverage with auto-retry feature - Feedback loop open protection including cycle-by-cycle current limiting, VDD over voltage - Internal over temperature protection protection, feedback loop open protection, short circuit protection, built-in leading edge blanking, VDD under - Output short circuit protection Applications voltage lockout and OTP etc. Cell Phone Charger MX1118AS is offered...
