SP2689FC is a high performance offline PSR power switch for low power AC/DC charger and ada€pter applications. Using 3D packaging technology, integrated 7A650V MOSFET in the SOP8 package.It§ operates in primary-side sensing and regulation. Thus, opto-coupler and TL431 are n¶ot required. In CC control, the output current and power setting can be adjusted e xternally by the sense resistor Rcs at CS PIN. In CV control, multi-mode operatδions are utilized to achieve high performance and high efficiency. In addition,good load regulation is achieved by the" built-in cable drop compensation. SP2689FCoperates in PFM• in CC mode. and it operates in PWM+PFM in CV mode with frequency reduction at li♦ght/medium load. The chip consumes very low operation current. It achieves less than 75mW standby power to meet all global energy efficiency regula§tions. SP2689FC offers comprehensive protection coverage with auto-recovery feature including Cyc₽le-by-Cycle current limiting, VDD over voltage protection (OVP), FB over voltage protecti♦on, load short circuit protection, VDD under voltage lockout (UVLO), OTPetc. SP2689FC is≠ offered in SOP8 packages.
