SP2689FC is a high performance o↕επffline PSR power switch for low power§β♠ AC/DC charger and adapter applic±'®ations. Using 3D packaging technology, '&σ€integrated 7A650V MOSFET in the SOP8 package.≤•πIt operates in primary-side sensi♥φng and regulation. Thus, o< "pto-coupler and TL431 are ₩ not required. In CC control, the output&✘↕Ω current and power settin✘↔γg can be adjusted externally by the senεπγse resistor Rcs at CS PIN. In CV cont¶∏rol, multi-mode oper ¶ations are utilized to achieve high performanc'→ &e and high efficiency. In addition,good load re←↔$gulation is achieved by the built-in cable drop c♠πompensation. SP2689FCoperates in PFM in€∞↓  CC mode. and it operates∏ ≠≠ in PWM+PFM in CV mode w↑₩ith frequency reduction at light/medφ&♠ium load. The chip consumes very low operat​✔δion current. It achieves less tπ÷han 75mW standby power to meet all global ene↑ ≈rgy efficiency regulations. SP2689FC ∑∏☆↕offers comprehensive₹γ≥ protection coverage with auto-recovery fe♣​ature including Cycle-by-Cycle current lim≠♠Ωiting, VDD over voltage protection (OVP), FB o'↔★ver voltage protection, load short circuit pr★™otection, VDD under voltage locφ☆kout (UVLO), OTPetc. SP2689FC is offereγ♦d in SOP8 packages.
