PROGRAMMABLE POWER SUPPLY

摘要

The present invention provides a method of programming a programmable power supply. In the method, a requesting signal is generated in a device, and the requesting signal is received in the programmable power supply. Then, an output voltage of the programmable power supply is determined in accordance with a frequency of the requesting signal. The output voltage of the programmable power supply is coupled to power a load of the device. A de-bounce operation is further provided for filtering noises of the requesting signal. The requesting signal comprises a high-state period and a low-state period. The high-state period is defined during which a level of the requesting signal is higher than a threshold. The low-state period is defined during which the level of the requesting signal is lower than the threshold. The output voltage of the programmable power supply is further determined by a period of the requesting signal.
