SP2689FC is a high performance®<"$ offline PSR power swit®γ★ch for low power AC/DC charπ'λger and adapter applications. Usin£♠☆γg 3D packaging techn₩€βology, integrated 7A650V MOSFET in t↔↕he SOP8 package.It operates in primar₽ &y-side sensing and reguΩ£♣λlation. Thus, opto-coupler and TL431 ε×₽¶are not required. In ∞↔​¶CC control, the output ♣δ↑γcurrent and power setting can be‍±" adjusted externally ∑'← by the sense resistor Rcs at CS PIN. &♥§φIn CV control, multi-m♠☆∞ode operations are utilized to ach™&ieve high performance and high e ×>fficiency. In addition,good ™εload regulation is achieved by ÷σγthe built-in cable drop compensati←&on. SP2689FCoperates in PΩ •FM in CC mode. and iσ•↕πt operates in PWM+PFM<$> in CV mode with frequency r♠™eduction at light/meβαdium load. The chip cons↑₹€umes very low operation current. It α♣achieves less than 75mW standby po≠¶£‌wer to meet all global e  ≠nergy efficiency regulatio☆≠¶εns. SP2689FC offers compre‍≠♦hensive protection co¶&ε₹verage with auto-recovery featu€≠®re including Cycle-by<φ✘>-Cycle current limiting, VDD over volt←λ♠ age protection (OVP), FB ov≠¶ er voltage protection, load shoβ±≠rt circuit protection, VDD under v∞♦¥≥oltage lockout (UVLO), OTPetc. SP268δ★& 9FC is offered in SOP8 packages.×$
