  • Constant gate-to-source-volt age-driving driver architecture for switched-mode power supplies
    Patent number: 11502599
    Abstract: Techniques and apparatus for supplying power to gate drivers of a switched-mode power supply (SMPS) circuit. One example power supply circuit generally includes a SMPS circuit having a first input voltage node and a second input voltage node, and a charge pump. The charge pump generally includes a first capacitive element having a first terminal and a second terminal; a first switch coupled between a first input node of the charge pump and the first terminal of the first capacitive element; a second switch coupled between the second terminal of the first capacitive element and a second input node of the charge pump; a third switch coupled between the first terminal of the first capacitive element and the first input voltage node of the SMPS circuit; and a fourth switch coupled between the second terminal of the first capacitive element and the second input voltage node of the SMPS circuit.
