SP2637AF is a high perfomanc÷ e offline PSR power switch for low ✘≤  power AC/DC charger and adapter appli→≤$cations. It operates in pri✘σ'mary-side sensing and'​δ regulation.Thus, opto-cΩ★•≤oupler and TL431 are not‌₹∑ required. In CC contro∑ β​l, the output current and power sett₹✘$ing can be adjusted extemally ∏§ by the sense resistor Rcs at CS PIN.↔♣♣  In CV control,multi-mode opeλ£♥rations are utilized to ach↕>€™ieve high performance and high eff÷€iciency. In addition, good loadσ→≠ regulation is achieved by the built-♠± $in cable drop compen₩σsation. SP2637AF operates in PFM→♥± in CC mode, and it op¥‌≈erates in PWM+PFM in CV mode with freqΩ♥₩✘uency reduction at light/me✔​₹Ωdium load. The chip consum€↑≤es very low operation curre↓$nt. It achieves less than 7 α5mW standby power to meet all glob >al energy efficiency reg&≤ulations. SP2637AF off•&♣ers comprehensive pr♠£×otection coverage with婧 auto-recovery feature including∏® ↓ Cycle-by-Cycle current₩↑‍ limiting, VDD over voltage prote§→↓§ction (OVP),FB over voltage ★§ protection,load short circuit p€παrotection, VDD under voltage lockout (U¶ε♠→VLO), OTP etc. SP2637AF is offered in S ↑&OP8 packages.
