SP2637AF is a high perfomance offline ÷&‍→PSR power switch for low ‍">power AC/DC charger and adapter appli↑γcations. It operates in primary-side se₽♥♥nsing and regulation.Thus, opto-coupler ​₩ and TL431 are not required. In C∑÷≥&C control, the output current and ÷©>power setting can be¥$γ adjusted extemally by the ✘↓☆δsense resistor Rcs at CS÷←∞ PIN. In CV control,multi-mod'←∏e operations are utiliz→☆αed to achieve high performance and hi>¥₹↑gh efficiency. In addition, goo♣""↓d load regulation is ach₩$←ieved by the built-in cable dו♦☆rop compensation. SP2637AF op♥₩erates in PFM in CC mode, andφεγ it operates in PWM+PFM in ≈ CV mode with frequency reduction at ∞™light/medium load. The chip consu≤∞≠πmes very low operation cu ​∏rrent. It achieves les÷≥✘πs than 75mW standby power to me₩ et all global energy ™‍efficiency regulations. SP ®2637AF offers comprehens‌♠λive protection coverage with auto-r≠₹♥ecovery feature including Cy♠‌  cle-by-Cycle current limiting, V★≤DD over voltage protection (OVP)  §,FB over voltage protection,load shor×₹​t circuit protection, ©€♦VDD under voltage lockout (UVLO), O ☆TP etc. SP2637AF is offered in SOP₩±8 packages.
