SP2689FC is a high performance of$σfline PSR power switch for low powe‌™₹r AC/DC charger and adapter applications. Usinσ×g 3D packaging technology, ♥​integrated 7A650V MOSFET in theε ✘¥ SOP8 package.It operates in p&©rimary-side sensing and regulation. Thus, opto-co©∞ upler and TL431 are not required. In CC cont♦₩÷≥rol, the output current and poπ♥&​wer setting can be adjusted externally πΩ by the sense resistor Rcs at CS PIN. In CV con δtrol, multi-mode operations a∞★re utilized to achieve high performance and high ≤≥‌efficiency. In addition,good load r$&egulation is achieved by the built-in cable drop ​☆≤compensation. SP2689FCoperates in PFM in C&♥C mode. and it operates in ©β↕εPWM+PFM in CV mode with freqβλuency reduction at light/mediu≈↑±m load. The chip consumes very low☆φ± operation current. It achieves leγ♣→ss than 75mW standby power to meet a≥♠₩ll global energy efficiency regulatioγ¥ns. SP2689FC offers comprehensive protection covσ​☆erage with auto-recovery feature including¶π Cycle-by-Cycle current limiting, ∞≈♣φVDD over voltage protection (OVP)σ¶, FB over voltage protection, load sh붙ort circuit protection§ε, VDD under voltage lockou •t (UVLO), OTPetc. SP2689FC is offered in αεSOP8 packages.
