SP2689FC is a high perfo∞φ ∑rmance offline PSR power switch for low power AC↔♦ /DC charger and adapβ‌ ∏ter applications. Using 3D packaging technol‌↕♦£ogy, integrated 7A650V MOSFET in ​γthe SOP8 package.It operates in primary-‍£side sensing and regulation. Thus, opto-coupler a→±©↕nd TL431 are not required.σ÷₽ In CC control, the output current a☆δ§↔nd power setting can be adjusted externally by t$δhe sense resistor Rcs at CS PIN. ∞¶≥In CV control, multi-mo♥σ‍de operations are util↑  ized to achieve high p ∞erformance and high efficiency.¶σ‍ In addition,good load regulation≤≤® is achieved by the bu<♥→≤ilt-in cable drop compensation​∞. SP2689FCoperates in PFM in CC mode.×♦  and it operates in PWM+PFM in©α CV mode with frequency reduction a₹γt light/medium load. The chip consumes ver¥‌∏​y low operation current. It achieves less∏<✔δ than 75mW standby power to meet all₽& global energy efficiency regulations. SP&<↓♥2689FC offers comprehensive protection co•↑♠​verage with auto-recovery feature in&<↕♦cluding Cycle-by-Cycle curre‍ nt limiting, VDD over voltage protection (≥↓♥↑OVP), FB over voltage protection, loa↓$d short circuit protection, VDD under volt♦←age lockout (UVLO), O©ε TPetc. SP2689FC is offered in S♣€OP8 packages.
