SP2689FC is a high performance offlin♠εγ↑e PSR power switch for low power AC★$/DC charger and adapter app<§¶lications. Using 3D packagin↑♣g technology, integrated 7Aγ↔♦650V MOSFET in the SOP8 package.I↕ε→t operates in primary-side sensing and★₽ regulation. Thus, opto-✔♦←↓coupler and TL431 are not requ§≥♠ ired. In CC control, the output c∑★±urrent and power setting can be aαπ☆§djusted externally b®​♣♦y the sense resistor Rcs at CS P​קπIN. In CV control, multi±↓-mode operations are utilized to achiev≈  e high performance and high effici♥♥™✔ency. In addition,good   load regulation is achieved by tεφhe built-in cable dr₩∑✘op compensation. SP2689FCoper↕γ∞ates in PFM in CC mode. and it ope←♦&rates in PWM+PFM in CV mode with freq‌αuency reduction at light/medium load. §§The chip consumes very lo®×α'w operation current. It ≤××achieves less than 75mW sta∏Ωndby power to meet all global en↑>"₽ergy efficiency regulatio‍ ‍€ns. SP2689FC offers comprehensive prot∏φection coverage with auto-reco€®βεvery feature includi←≈& ng Cycle-by-Cycle current limiting, V→φDD over voltage protectio↔♥‌n (OVP), FB over voltage γ&protection, load shor​±δ€t circuit protection, VD→★≠φD under voltage lockout (UVLOφ↕), OTPetc. SP2689FC is offered in S∑₩'OP8 packages.
