Title:
POWER SUPPLY DEVICE AND WORKING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2016/082716
Kind Code:
A1
Abstract:
A power supply device and a working method thereof. The device comprises a power supply E, a DC-DC converter (1), a data output buffer (2), and a voltage detector (3). The power supply E is used to supply power to the DC-DC converter (1) and the data output buffer (2). The DC-DC converter (1) is used to convert a voltage output by the power supply E and then supply power to a load. The voltage detector (3) is used to detect an output voltage of the DC-DC converter (1), and when it is detected that the output voltage is higher than an upper limit value or is lower than a lower limit value, the voltage detector (3) controls the DC-DC converter (1) to be disconnected from the load, detects a voltage at a load end, and controls the data output buffer (2) to output a voltage and supply power to the load. The device can use the data output buffer to implement the function of a backup power supply converter, and effectively reduces costs.
