Problems solved by technology

When the host system must be equipped with a transformer with high rated power, it will inevitably increase the manufacturing cost and lead to a decrease in competitiveness
In addition, transformers usually with high power ratings are relatively large and not suitable for applications in microcomputers, tablet computers, and thin notebook computers

Abstract

The invention discloses a power adjuster, which is suitable for adjusting the operating frequency of a central processing unit. The power adjuster includes a power resistor, a voltage amplifier and an analog-to-digital converter. The power resistor is coupled to the load to generate the first voltage. The voltage amplifier is coupled to the power resistor to output the second voltage. The analog-to-digital converter is coupled to the voltage amplifier and converts the second voltage into a control signal. The analog-to-digital converter transmits a control signal to the CPU, and the control signal can be switched between a first level and a second level.

Description

technical field [0001] The invention relates to a power regulator, especially a power regulator suitable for a central processing unit. Background technique [0002] Based on the requirements of electronic product safety regulations, the total power consumed by the host system cannot exceed the rated power of the transformer attached to the host system. Due to the increasing demand of consumers for the expansion of external devices, the number of USB connection ports designed by many host systems must also continue to increase. Relatively, the transformer of the host system must be designed to have a higher rated power. Only in compliance with electronic product safety regulations. For example, for an electronic product with a rated power of 65W, the total power of the system will be changed to 67W due to the increase in the number of USB connection ports. In this way, the 65W transformer used in the product must be changed to a 95W transformer. When the host system must ...
