Problems solved by technology

However, the added capacitor has an impact on the existing power supply and the layout of the processor on the motherboard. In one technology, the capacitor is placed on the surface of the motherboard, and the circuit between the capacitor and the processor itself will introduce path loss and reduce processing. The energy efficiency of the device; in another technology, the capacitor is integrated in the processor, which will increase the circuit complexity of the processor, thereby increasing the design and implementation cost of electronic equipment

Abstract

The invention provides an electronic device. The transient response of a first power supply is improved through a compensation power supply circuit, and the current required by the first power supply during the transient response is compensated through a power supply with a higher switching frequency. Therefore, when the electronic device overcomes the transient response, the requirements of reducing DCR loss, reducing packaging cost and improving compensation efficiency are met at the same time. The first power supply or the compensation power supply circuit does not need to be packaged in a load on the basis of realizing high-efficiency compensation on the transient response of the first power supply through the compensation power supply circuit, and the design and implementation cost of the electronic device is further reduced.

Description

technical field [0001] The present application relates to electronic technology, and in particular to an electronic device. Background technique [0002] With the continuous development of electronic technology, the integration and operating frequency of processors and other devices in electronic equipment continue to increase, and the required operating current is also increasing. design requirements. Among them, improving the transient response of the processor and improving the energy efficiency of the processor are the main problems that the power supply needs to solve. When the operating current required by the processor changes in a step-like manner, the power supply usually cannot immediately output the large current required by the load. The current will cause a short-term drop in the output voltage of the power supply to the processor. Although the voltage will gradually return to normal after a period of time, the short-term drop in the output voltage of the power...
