  • Voltage regulation circuit
    Patent number: 9625933
    Abstract: A switchable voltage regulation circuit includes a power supply chip and a voltage regulation module. The voltage regulation module includes first and second resistors and first and second switch units. A first terminal of the first resistor is electrically coupled to a power supply and a first output pin of the power supply chip. A first terminal of the second resistor is electrically coupled to the second terminal of the first resistor. The first switch unit is electrically coupled between the first terminal of the first resistor and the second terminal of the first resistor. The second switch unit is electrically coupled between the first terminal of the second resistor and the voltage output. By manual switching, or by transistors under control of a baseboard management unit, the resistances can be switched in or switched out to regulate the voltage.
