SP2689FC is a high performance offl✔‌≈©ine PSR power switch for low ₽λpower AC/DC charger and adapte™ ‍✘r applications. Usin™​g 3D packaging technology, integrated 7A650V Mσ★OSFET in the SOP8 package.It opera₹♥&&tes in primary-side sensing and regulation. Th>←us, opto-coupler and TL431 are not req←₹‌uired. In CC control, the output current₩φ& and power setting can be adjusted ext¥§ernally by the sense resi•£ >stor Rcs at CS PIN. In CV control, multi-mode"♥σ operations are utilized to achieve high ¥ ₩★performance and high effi≥∏↑‍ciency. In addition,good load regulatio±↕≈ n is achieved by the built-in cable drop com‌±pensation. SP2689FCoperates σ≥☆ in PFM in CC mode. ¶←→∞and it operates in PWM+PFM in CV mode §±© with frequency reduction at lighσ∑∑t/medium load. The chip consumes v÷σ£ery low operation current. It  αachieves less than 75mW standby pow÷∞er to meet all globa₹ εl energy efficiency regulations. SP2689FC o>↔®ffers comprehensive protectio×£σn coverage with auto-recovery feature inc★←↔ luding Cycle-by-Cycle current limiting, VDD"® over voltage protection (OVP), FB over♣¥☆ voltage protection,≤↕ load short circuit protβ →>ection, VDD under voltagπ₽§e lockout (UVLO), OTPetc. SP26♥₹≥Ω89FC is offered in SOP8 packages.
