SP2689FC is a high per♥¶​€formance offline PSR po★α§σwer switch for low power AC/DC‍↓¥ charger and adapter applicati♥₩<↔ons. Using 3D packaging techno✔÷•logy, integrated 7A650V MOβ£SFET in the SOP8 package.It operates in∏✘☆ primary-side sensinΩ∏g and regulation. Thus, op∞♣πto-coupler and TL431 are not re  ​εquired. In CC control, the output curr☆'•ent and power setting can be₹✔& adjusted externally by the s♦εφense resistor Rcs at CS PIN. In CV con₹γ€£trol, multi-mode ope©↔™rations are utilized to achieve$↔☆' high performance an××β≤d high efficiency. In addition,goo±λ♦d load regulation is achieved bγ∞•♣y the built-in cable drop compensΩ≈☆₽ation. SP2689FCoperates in PFM in CC φ₽mode. and it operatesλ" ' in PWM+PFM in CV mode with>€₩ frequency reduction at↔​✘ light/medium load. The chip coσ nsumes very low operation current. It ₩σ↓achieves less than 75mW standby powe∑©r to meet all global energy ef‌✘©ficiency regulations. SP2689FC of↓βλfers comprehensive protection®≤Ω coverage with auto-recovery fe₽  ature including CyclΩ€←≠e-by-Cycle current limiting, ♥₩£VDD over voltage pro≤≤δ®tection (OVP), FB over vo&↑ltage protection, load sh €δσort circuit protecti •₩on, VDD under voltage lockout (UVLO),'↕ OTPetc. SP2689FC is offered in SO‍→•¶P8 packages.
