SP2689FC is a high perfor↔β©mance offline PSR power switch for low powe♣‌÷εr AC/DC charger and adapter a≤≤pplications. Using 3D packaging technology, i∏↓‍ntegrated 7A650V MOSFET in th© ≥£e SOP8 package.It oper<¶ates in primary-side sensing and regulat​≠≈✔ion. Thus, opto-coupler and TL431 are not★φ required. In CC control, the output current π'>and power setting can be adjusted externally‮₹ by the sense resistor Rcεεs at CS PIN. In CV control, mu≠ βlti-mode operations are utilized to achi☆™λeve high performance and high efficiency. In←< addition,good load regulation is achie€↔ved by the built-in cable drop compensation.✘<< SP2689FCoperates in PFM↔₹✘☆ in CC mode. and it operates in PWM+PFM in σ≈βCV mode with frequency r ♠•eduction at light/medium≤↕ load. The chip consumes verε©y low operation current. It achieves les♥>≈¥s than 75mW standby power to €£€≠meet all global energδ&y efficiency regulations. SP26♦∞89FC offers comprehensive protection coverage §★₩≈with auto-recovery feature including Cy£¥cle-by-Cycle current limiting, VDD over v♠∏↕ oltage protection (OVP), FB over voltage protect&÷¶σion, load short circuit protection, VDD und★×er voltage lockout (UVL×≤€<O), OTPetc. SP2689FC is of πfered in SOP8 packages.
