SP2689FC is a high performa₽♦<nce offline PSR power switc©•h for low power AC/DC charger and≥©↕ adapter applications. Usin±★g 3D packaging technology, in♥'tegrated 7A650V MOSFET in '¥φthe SOP8 package.It operate↑♠s in primary-side sensing and regu​→<★lation. Thus, opto-coupler ≈ $and TL431 are not required.♥<> In CC control, the output currentγ ± and power setting can be adjusted ext―ernally by the sense↔≥δ♣ resistor Rcs at CS PIN. In CVα↑σ' control, multi-mode operat"÷ions are utilized to achieve high perfo↓↕★±rmance and high effi®★ciency. In addition,good loa≈π‌d regulation is achieved by theΩ★ built-in cable drop compensa♥±£φtion. SP2689FCoperates in PFM in ₩ CC mode. and it operates in PWM+P≤§FM in CV mode with frequency reduction α"↑​at light/medium load. The chip ¥₽Ω∞consumes very low oper★¥ation current. It achieve≤$→↕s less than 75mW sta‌Ω ndby power to meet all ®×σglobal energy efficiency regulations.∞✔ SP2689FC offers comprehensive ↓←$protection coverage with auto-r∑∏σecovery feature including Cycle-by£>☆-Cycle current limiting, VDD over vol ≥‍tage protection (OVP), FB over voltageδλ protection, load sh  ♣ort circuit protectiΩ↕>on, VDD under voltage lockout (UVLO™☆♦>), OTPetc. SP2689FC is of✘≠™fered in SOP8 packages.
