D8537F SOP7 PSR IC+MOSFET 10W

  D8537F is a high performance offline PWM Controller for low power AC/DC charger and adaptor applications. It operates in primary-side sensing and regulation mode. Consequently, TL431 and opto-coupler could be eliminated. In Constant Current(CC) control, the current and output power setting can be adjusted externally by the sense resistor Rcs at CS pin. In Constant Voltage(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.D8537F operates in PFM in CC mode, and it operates in PWM+PFM in CV mode 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. D8537F offers comprehensive protection coverage with auto-recovery feature including Cycle-by-Cycle current limiting, VDD Over-Voltage Protection(OVP), feedback loop open protection, short circuit protection, Under-Voltage Lockout(UVLO),OTP etc. D8537F is offered in SOP7 package
