SP2689FC is a high performance offlin✔<&↕e PSR power switch for low power AC/DC cha♦©rger and adapter applications. Using 3D pac Ωδkaging technology, integrated 7A650V ₩★ε MOSFET in the SOP8 package.It oper‌ ates in primary-side sensing and reg'₽ulation. Thus, opto-cou₽•₹pler and TL431 are not required. In CC ¶‍control, the output ¶ ₩current and power setting can be adjus✔↓≥≥ted externally by the sense resistor Rcs at CS PI♠↑N. In CV control, multi-mode oper'αations are utilized to achieve high p÷≥↕✔erformance and high efficiency. In addition,go₹¶✔od load regulation is ach₽∏₩ieved by the built-in cable drop co&©↕mpensation. SP2689FCoperates in PFM i✘→≥n CC mode. and it operates in PWM←εγ¥+PFM in CV mode with frequency reduct∏≠≥ion at light/medium load. The chip consumes v¥≤>ery low operation current. Itλ¥♣∞ achieves less than 75mW standby power ™φ<to meet all global energy efficiency regulations.♥× SP2689FC offers comprehensive protec§×&♣tion coverage with auto-recovery featu≤←®re including Cycle-by-Cycle current limitingΩ↓, VDD over voltage prot∏↑​ection (OVP), FB over voltage protecti​∏on, load short circuit protection, VDD under v>↓oltage lockout (UVLO), OTPetc. SP2689FC is off→×ered in SOP8 packages.
