SP2689FC is a high performance offline PSR power switch for low power AC/DC charger$ and adapter applications. Using 3D packaging technology, ‍integrated 7A650V MOSFET in the SOP8 package.It operates in pri×mary-side sensing and regulation. Thus, opto-coupler and TL431 are not required. In CC♣ control, the output current and power setting can be adjusted externally by the sense resistor ≠Rcs at CS PIN. In CV control, multi-mode operations arαe utilized to achieve high performance and high efficiency. In addition,good load ≤regulation is achieved by the built-in cable drop compensation. SP2689FCoperates£ 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 achieveβs less than 75mW standby power to meet all global energy efficiency regulations. SP2689FC "offers comprehensive protection coverage with auto¶-recovery feature including Cycle-by-Cycle current limiting, VDD§ over voltage protection (OVP), FB over voltage protection, loa®d short circuit protection, VDD under voltage lockoutσ (UVLO), OTPetc. SP2689FC is offered in SOP8 packages.
