SP2637AF is a high perfomance offli∞Ωne PSR power switch for low §​power AC/DC charger and adapter appl↓₽ε≤ications. It operate≤♠¥‌s in primary-side sensing a₩♠>♠nd regulation.Thus, opto-coupler and★>&→ TL431 are not required. ∞✔≥In CC control, the out> put current and power setting can ↕Ω‌be adjusted extemally by the s Ωσφense resistor Rcs at CS PIN. Inφ♣★← CV control,multi-mode operations ar≠₩£e utilized to achieve high performan>™₹♥ce and high efficiency.₩✘$ In addition, good lo¥β©ad regulation is achieved by the b☆≈>uilt-in cable drop compe>₹nsation. SP2637AF operates in ♥♠‍PFM in CC mode, and it operatesσ₹↕ in PWM+PFM in CV mode with frequency r¶®☆'eduction at light/medium load♣‍σ. The chip consumes very•≤' low operation curre★$∏nt. It achieves less than 75mWδφ standby power to meet all ±®global energy efficiency ​​↔γregulations. SP2637AF off€♦₽ers comprehensive protection co δ∞€verage with auto-recovery feature inclu₽ ∑♦ding Cycle-by-Cycle current limiting, ©≠VDD over voltage protection (OVP),FB‍≥✔ over voltage protect↓≥ion,load short circuit protecti♠× ≠on, VDD under voltage lockout (UV≠δλLO), OTP etc. SP2637AF is ≈ offered in SOP8 packages.
