MX1110T Datasheet | MAXINMICRO

FEATURES MX1110T is high performance offline PSR power switch for - Primary side sensing and regulation without PC817 and low power AC/DC charger and adapter applications. It TL431 operates in primary side sensing and regulation. Consequently, - High precision CC and CV at universal AC input opto-coupler and TL431 could be eliminated. Proprietary - Multimode operation for efficiency improving constant voltage and constant current control is integrated as - Programmable CC and CV regulation shown in the figure below. - Built-in primary winding inductance pensation In CC control, the current and output power setting can be - Programmable cable drop pensation adjusted externally by the sense resistor Rcs at CS pin. In CV - No need for control loop pensation control, multimode operations are utilized to achieve high - Audio noise free operation performance and high efficiency. In addition, good load - Ultra-low start up current and low operating current regulation is achieved by the built in cable drop pensation. - Built in leading edge blanking (LEB) Device operates in PFM in CC mode at large load condition - prehensive protection coverage with auto-retry and it operates in PWM with frequency reduction at - VDD Under Voltage Lockout with hysteresis (UVLO) light/medium load. The chip consumes very low operation - VDD Over Voltage Protection (VDD OVP) current. It achieves less than 75m W standby power to meet - Cycle-by-cycle over current protection strict standby power standard.MX1110T offers prehensive - Feedback loop open protection protection coverage with auto-retry feature including cycle- - Internal over temperature protection by-cycle current limiting, VDD over voltage protection, feedback loop open protection, short circuit protection, built- - Output short circuit protection Applications in leading edge blanking, VDD under voltage lockout and OTP Cell Phone Charger etc. Auxiliary Power Adapter for TV, PC etc. MX1110T is...
