Abstract

The invention belongs to the field of power supply control and provides a power supply control circuit and a power supply device. Through adopting the power supply control circuit comprising a first voltage stabilizer, a second voltage stabilizer, a diode D1 and a diode D2, through carrying out voltage stabilization processing on direct currents output by a DC power supply through the first voltage stabilizer and the second voltage stabilizer, and through carrying out confluence on the processed direct currents through the diode D1 and the diode D2 and outputting the combined current to realize large current output, the purpose of supplying power to or charging the high-power load is realized.

Description

technical field [0001] The invention belongs to the field of power supply control, in particular to a power supply control circuit and a power supply device. Background technique [0002] At present, the output current of many low-voltage power supply devices (such as chargers or battery packs) is small, and the current value is about 500mA, which can generally only be used to charge mobile phones or other small loads. For a large-loaded device such as a tablet computer, the power supply device needs to output a power supply current of 1A to 2A to meet the charging requirement. Therefore, the existing power supply device cannot achieve high current output to meet the power supply and charging requirements of high-power loads. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a power supply control circuit, which aims to solve the problem of the existing power supply device that cannot achieve high current output to meet the power supply ...
