SP2689FC is a high performance offline P​≤↑✘SR power switch for low ₹€₩power AC/DC charger a♦λnd adapter applications. Usin ‌≥g 3D packaging technology, integ£>↔rated 7A650V MOSFET in t±≥<£he SOP8 package.It opera¶•​tes in primary-side sensing and regulation. Thus¶απ★, opto-coupler and TL431 are not require₽'α>d. In CC control, the out≤↕put current and power setti¶ ≈ng can be adjusted externa≠★β>lly by the sense resistor Rcs  ±♦πat CS PIN. In CV control, multi-mod↔©∏e operations are utilized to achieve high δ↓↑performance and high efficiency. In ad♠​​dition,good load regulation is ach✘ ♦☆ieved by the built-in cable drop compensat¶↔π'ion. SP2689FCoperates in PFM in CC mode. and iδ¶t operates in PWM+PFM in CV mode with f ↑✘Ωrequency reduction at light/medium lo↑↓≈ad. The chip consumes very low operation curr "♥ent. It achieves less than 75mW sΩ‍¥ tandby power to meet all global energy efficiencyε↓≈± regulations. SP2689FC offers comprehensive↑×★ protection coverage with auto-recαα↑£overy feature including Cycle-by-Cycle  ∏current limiting, VDD over vol★®☆tage protection (OVP), FB over voltage↑©×÷ protection, load short circuit protection, γ£✔VDD under voltage lockout (¶✔♦UVLO), OTPetc. SP268♠™9FC is offered in SOP8 packa‍σ₽ges.
