SP2637AF is a high perfomance offlin§§ e PSR power switch for low power AC/DC ε charger and adapter applicatio↕σ←ns. It operates in pri←ε♦≥mary-side sensing and• ¶↑ regulation.Thus, opto-coupler and TL43 ≤↔ 1 are not required. In CC control, the  ασ∏output current and power settinα∏g can be adjusted extemally by the sens§‍γe resistor Rcs at CS PIN.Ω∞ In CV control,multi-moφφ♦de operations are utilize♦←♦≠d to achieve high performance aΩ β☆nd high efficiency. In addit♥& ion, good load regulation is achi≤φ↕>eved by the built-in cable drop compe↕₩€♥nsation. SP2637AF operates in§' ₽ PFM in CC mode, and it operates in P♣$ WM+PFM in CV mode with frequency reduct↓♠ion at light/medium load. The c✔✔✔∞hip consumes very low operation current&€§←. It achieves less than 75mW standby pα$ower to meet all globα₹al energy efficiency regulaφ•<tions. SP2637AF offers ₹∏ comprehensive protection cove>®$rage with auto-recove≥÷±≠ry feature including Cyγ'cle-by-Cycle current limiting, VDD o≈ &¶ver voltage protection (OVP),FB ove​∏♦r voltage protection,load short circuitφε§γ protection, VDD under voπ←∞ltage lockout (UVLO), OTP etc. SP26→≈≥λ37AF is offered in SOP8 p¶±©®ackages.
