Patent ID: 8723485

Claim:
A power supply system, for providing a power signal to a first load device, comprising: a first output node, coupled to the first load device; a first internal power supply unit, comprising: a first gold capacitor unit, for storing a first internal storage voltage; a first boost storage unit; a first charging path unit, being turned on in a first charging period for providing the first internal storage voltage to the first boost storage unit, which correspondingly stores a first boost supply voltage; a first discharging path unit, being turned on in a first discharging period for serially connecting the first boost storage unit and the first gold capacitor unit between the first output node and a reference voltage, to provide the power signal for driving the first load device according to the first internal storage voltage and the first boost supply voltage, wherein the first charging period and the first discharging period are non-overlapping and a boost/buck unit, for receiving the first internal storage voltage and accordingly charging the first boost storage unit, which correspondingly stores the first boost supply voltage.
