SP2689FC is a high performance off←☆₹≈line PSR power switch for low power AC/DC c♠↔σ≠harger and adapter applicatio₽¶λns. Using 3D packaging technolog✘★y, integrated 7A650V MOSFET in the¥★♥ SOP8 package.It operates in primary-side s¶₹•ensing and regulation. Thus, opto-couple↕π♥r and TL431 are not requ∞≤↓αired. In CC control, the output curre>>' nt and power setting can be adjusted exΩ€↓ternally by the sense resistor Rcs at CS PIN. &∑ In CV control, multiβ ↓-mode operations are utilized to ach§©↓ieve high performance and high efficiency&σΩ. In addition,good load regulation i ☆s achieved by the built-in cable d✔✘rop compensation. SP2689FCoperates in ↓≥φ<PFM in CC mode. and it operates in π₽PWM+PFM in CV mode with frequency reduction at §π×"light/medium load. T★♠±he chip consumes very low operatio≈<n current. It achieves less than 7↑€5mW standby power to m♠§eet all global energy efficiency re​&gulations. SP2689FC ™∏≈offers comprehensive protection coverage with a®✔uto-recovery feature including Cycle-by-Cπ¶✘<ycle current limiting, VDD over ×®γ§voltage protection (OVP), FB over v☆✔σoltage protection, load short circuit pro♣πtection, VDD under voltage lockout (UV•"&πLO), OTPetc. SP2689FC is offered in SOP8 pa♠∏¶ckages.
