Power supply system
First Claim
1. 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, whereinthe first charging period and the first discharging period are non-overlapping anda 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.

Abstract
A power supply system includes an output node, an internal power supply unit, a boost storage unit, a charging path unit, and a discharging path unit. The output node is coupled to a load device. The internal power supply unit includes a gold capacitor unit for storing an internal storage voltage. The charging path unit is turned on in a charging period to store a boost supply voltage in the boost storage unit. The discharging path is turned on in a discharging period to provide a power signal for drive the load device according to the internal storage voltage and the boost supply voltage. The charging and discharging periods are non-overlapping.
