AXElite AX2535
AX2535 is a high performance offline PWM Power switch for low power AC/DC charger and adapter applications. It operates in primary-side sensing and regulation. m Û V power on soft AX2535 offers omstart control and protection coverage with c .GENERAL DESCRIPTION
Consequently, the photo-coupler and TL431 could be eliminated. Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrated as shown in the figure below. In CC control, the current and output power setting can be adjusted externally by the sense resistor RS at CS pin. In CV control, multi-mode 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 as well at large b Ñ y● load condition and it operates w`R in PWM with frequency reduction at light/medium load. h cCycle-by-Cycle auto-recovery features including current limiting, VDD OVP, VDD clamp e t o f and UVLO. Excellent EMI performance is achieved by frequency shuffling technique. .go w w High precision w constant voltage (CV) and constant current (CC) can be achieved by AX2535. VO ± 5% IO ICC Fig.1.
