Controller IC Chip - High-Performance Notebook PWM Controller MOSFET APW8814QBI-TRG APW8814 8814 chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0308) The APW8814 is a single-phase, constant-on-time, synchronous PWM controller, which drives N-channel MOSFETs. The APW8814 steps down high voltage to generate low-voltage chipset or RAM supplies in notebook computers. The APW8814 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the APW8814 provides very high efficiency over light to heavy loads with loading-modulated switching frequencies. In PWM Mode, the converter works nearly at constant frequency for low-noise requirements. The APW8814 is equipped with accurate positive current-limit. output under-voltage, and output over-voltage protections. perfect for NB applications. The Power-On-Reset function monitors the voltage on VCC and PVCC to prevent wrong operation during power-on. The APW8814 h
