SP2689FC is a high performance offline P↑>‍λSR power switch for low po≥ ¥φwer AC/DC charger and adapter application¶​π±s. Using 3D packaging technolo☆≠σgy, integrated 7A650V MOSFET"↑€ in the SOP8 package.It operates in pri≈αmary-side sensing and regu®∑βλlation. Thus, opto-coupler and TL431 are not ↑ required. In CC control, the output curr→✘ ent and power setting ca ‌n be adjusted externally by the sense resiλ÷ ®stor Rcs at CS PIN. In CV contr ¶✔ol, multi-mode operationγ↓→s are utilized to achieve high performanc←∞<∏e and high efficiencyαλ. In addition,good load reg≥Ω≠ulation is achieved by λδπthe built-in cable drop compensa✘×¥tion. SP2689FCoperates in¶δ" PFM in CC mode. and it ope♣​÷$rates in PWM+PFM in CV mode with frequ​¶φency reduction at light/medium load. The ch₽φβ'ip consumes very low operationεα↔ current. It achieves less than 75mW standby powe  ☆§r to meet all global energ♥✘​↑y efficiency regulations. SP2689FC oα​₹ffers comprehensive proteλ≤∏ction coverage with auto-recovery feature includε≠←ing Cycle-by-Cycle current limiting, V​≈DD over voltage protection (OVP), FB over voltage∑φ® protection, load sho₩≠rt circuit protection, VDD under  ♠≤voltage lockout (UVLO),₽<σ♥ OTPetc. SP2689FC is offered in SO☆¶P8 packages.
