Controller IC Chip - Synchronous Buck Controller MOSFET APW8813A APW8813 chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0307) The APW8813/A integrates a synchronous buck PWM controller to generate VDDQ. a sourcing and sinking LDO linear regulator to generate VTT. It provides a complete power supply for DDR2 and DDR3 memory system. It offers the lowest total solution cost in system where space is at a premium. The APW8813/A provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM). the APW8813/A provides very high efficiency over light to heavy loads with loading-modulated switching frequencies. On TQFN4x4- 24A package. the Forced PWM Mode works nearly at con-stant frequency for low-noise requirements. The APW8813/A is equipped with accurate current-limit, output under-voltage. and output over-voltage protections. A Power-On-Reset function monitors the voltage on Vec prevents wrong operation during po
