SP2637AF is a high perfomanc÷×‌e offline PSR power swi±≠tch for low power AC/"↑DC charger and adapter application±"s. It operates in primary-s≥≥↑×ide sensing and regulation.Thus, opto-®¥≈★coupler and TL431 are not req£​uired. In CC control, th≥©&♠e output current and power setting can γ↓be adjusted extemally by the sense ✔≈¥resistor Rcs at CS PIN. ✘​ ✔In CV control,multi-m✘∑∑•ode operations are utilized to achie≤♦✘πve high performance and high effici★≈€ency. In addition, gα×λood load regulation is achieved by the ¥<←&built-in cable drop compe←☆§₹nsation. SP2637AF opera↓≥×δtes in PFM in CC mode,  ↔and it operates in PWM+PFM in CV mode'®±β with frequency reduction at lighπ≤±‍t/medium load. The chip consumes ver ∞y low operation current. It ach≈→₹♥ieves less than 75mW standby powe ★Ωr to meet all global energy efficien↕∞§cy regulations. SP2637AF offersσ∏ comprehensive protection coverage wit∑∞ h auto-recovery feature including C↑♣ycle-by-Cycle current limiting, VDD o÷‌ver voltage protection (OVP),FB over £πvoltage protection,load short ci★®rcuit protection, VDD under volta≤✔Ω​ge lockout (UVLO), OTP‌α≥£ etc. SP2637AF is offered in SOP© ♠8 packages.
