SP2689FC is a high per←∞ε★formance offline PSR p∏ ±ower switch for low '★‍power AC/DC charger and adapter Ω  applications. Using 3D packagi‌​ng technology, integrated 7A650V MO‌¶SFET in the SOP8 package.It op✘€®‌erates in primary-side ∞'sensing and regulation. Thusδ¶↑, opto-coupler and TLδε☆ε431 are not required. In CC ♣•control, the output current a≈‌‍nd power setting can be adjusted externπ "₹ally by the sense resistor Rcs¥εβ  at CS PIN. In CV con×λtrol, multi-mode operations ∑ ≈are utilized to achi₹₹©eve high performance and high §↑α↕efficiency. In addition,good load '↕regulation is achieved by the bu©​≥ilt-in cable drop com♦ ≥pensation. SP2689FCoperates≤₩ in PFM in CC mode. ☆'and it operates in PWM+PFM in CV mo$₽Ω♥de with frequency reduction at light/≥β'medium load. The chiπ•δp consumes very low ope‍‌α±ration current. It achieves less Ωβ than 75mW standby power to δ→÷meet all global energy efficiency ÷®₹regulations. SP2689FC of®₹★fers comprehensive protection ☆§&∞coverage with auto-recovery feature i ©♣↑ncluding Cycle-by-Cycle cur£✘ rent limiting, VDD o× ver voltage protection (OVP), FB ov←‌er voltage protection, load short cir'₹♠cuit protection, VDD unde☆λr voltage lockout (UVLO), OTPetc. SP2≈>φ¶689FC is offered in SOP8 packa≈≤≈ges.
