SP2689FC is a high perfor×σ₩mance offline PSR power€>≈• switch for low power AC/DCβΩ↓ charger and adapter applica™♦₹★tions. Using 3D packaging<±≈ technology, integrated 7A650 €♣V MOSFET in the SOP8 ♦σpackage.It operates in primary-¥εside sensing and regulat₹©δφion. Thus, opto-coupler and TL431∞"  are not required. In CC co←≥₹ ntrol, the output current and power ♥↔₹♦setting can be adjusted externally b ​y the sense resistor Rcs a<'™≈t CS PIN. In CV control, mu←≥ ✔lti-mode operations are✘♠‌♣ utilized to achieve high performance ≠←and high efficiency. In additionδ≠£,good load regulation π∑★≥is achieved by the built-in cab✔≥le drop compensation. SP2689FCoperates ✔$in PFM in CC mode. and it operates iΩ>♣→n PWM+PFM in CV mode wit×αΩ h frequency reduction at light/medium β™×$load. The chip consumes very low ​♦operation current. It achieves less‍€∏× than 75mW standby p$φ'ower to meet all global energy efficien↔γ≥πcy regulations. SP2689FC offers compr€£ehensive protection co↕←σ←verage with auto-recovery feature ↓÷including Cycle-by-Cycle current liσ§miting, VDD over voltage protection (→>δγOVP), FB over voltag&¶♣e protection, load sh₹★ort circuit protection, VDD un♣☆→αder voltage lockout (UVLOβεφ), OTPetc. SP2689FC is of↔₹$fered in SOP8 packages.
