SP2637AF is a high perfomance offlinσ₹₹e PSR power switch for low power AC/DC charge×★r and adapter applic"♥↑ations. It operates iδ∞‍n primary-side sensing and regu←σlation.Thus, opto-coupler and TL431 ₩∞≈>are not required. In CC control, the o‌₩utput current and power setting can ¶♥be adjusted extemally by the sense resisto§γr Rcs at CS PIN. In CV control,multi-modπ•®e operations are utilized to achieve high p≤♠↑erformance and high efficiency. In addition,λ→♣ good load regulation is achieved by the≠♥ built-in cable drop compensa₽‍πtion. SP2637AF operates in PFM±≤✔ in CC mode, and it operates in PWM+PF£§M in CV mode with frequency reduction a &₹t light/medium load. The chip consumes very®♦© low operation current. It achieves less than 75m★→☆W standby power to meet β​ all global energy efficiency regulations. SP2‍®637AF offers comprehensive protection coverage wi÷¥☆↑th auto-recovery feature inclu÷ ™ding Cycle-by-Cycle cu↔✔↕¥rrent limiting, VDD over v$‌×oltage protection (OVP),FB over v≤£oltage protection,load short ciγ§‌±rcuit protection, VDD under&∑ voltage lockout (UVLO), OTP •¥etc. SP2637AF is offered in SOP8 packages.✘↓≈
