SP2689FC is a high per≠≥♦→formance offline PSR power≤  ε switch for low power AC/DC↓φ← charger and adapter applications≠→¥ε. Using 3D packaging technology, in€↓∑∑tegrated 7A650V MOSFET i¶↓n the SOP8 package.It operates inδ✔ primary-side sensing and re'φ gulation. Thus, opto-coupler and T" ®L431 are not required. ™←☆φIn CC control, the output cε urrent and power setting can be ad↓♣ε€justed externally by the "®sense resistor Rcs at CS PIN. In C★♥¶V control, multi-mode o↑₽↑​perations are utilized to achieve ≠✔ high performance and high e§€​fficiency. In addition,good load≥¶ regulation is achieved by the b®'✔±uilt-in cable drop compensa©₽tion. SP2689FCoperates in PFM in C¶×γ♥C mode. and it operates in PWM+PFM §♣<in CV mode with frequency≠✘★ reduction at light/medium load. βφThe chip consumes ver£πy low operation current. It acδ∑≥hieves less than 75mW s↕±πδtandby power to meet •₩all global energy efficienc♦¶∏y regulations. SP2689F₹→•C offers comprehensive protection cover¥‍​€age with auto-recovery feature ¥♠£including Cycle-by-Cycle®♠ current limiting, VDφ→γD over voltage protection (OVP), FB ≈→£over voltage protection, l♥εoad short circuit protection, VDD♦§ under voltage lockout (UVL±∞₩O), OTPetc. SP2689FC is¶↓★ offered in SOP8 package§€s.
