SP2689FC is a high pe¥₩φrformance offline PSR÷π↓→ power switch for low power AC/DC↓♦≈ charger and adapter applications. ™ Using 3D packaging technolog©↕λ"y, integrated 7A650V‌€π MOSFET in the SOP8 packaπ∑ge.It operates in primary-side ε¥sensing and regulation. Thus, opt≥₩☆o-coupler and TL431 are&​® not required. In CC control,•€✔ the output current and ≥↔power setting can be adjusted ex"£¶÷ternally by the sense resistor Rcs a₩αt CS PIN. In CV contr$♦✘ol, multi-mode operations are★÷¶ utilized to achieve high perf>εormance and high efficiency.★→♥± In addition,good load regulati<≤¶on is achieved by the built-in  £♠cable drop compensati®$•↕on. SP2689FCoperates i‌Ω‍n PFM in CC mode. and it o£§¥βperates in PWM+PFM in CV €∑ ¥mode with frequency reduction at light/β₹medium load. The chip consumes very $✔¥≥low operation current. It achi↔¶eves less than 75mW standby power α↕÷to meet all global energy ¶​efficiency regulations. SP2689FC£σφ offers comprehensive pro>₹tection coverage with auto-recovery f¶ ×eature including Cycle-by-←♥♥Cycle current limiting, VDD over volta ‌≠ ge protection (OVP), FB over voltage pr ↑®✘otection, load short cirΩ'β×cuit protection, VDD∏"≠ under voltage lockout¶♦ (UVLO), OTPetc. SP2689FC is o₩¥ffered in SOP8 packages.
