Charge pump power ic
WebCharge pumps are used for gate-driving high-side n-channel power MOSFETs and IGBTs. When the centre of a half bridge goes low, the capacitor is charged through a diode, and this charge is used to later drive the gate of the high-side FET a few volts above the source voltage so as to switch it on. WebJul 12, 2024 · In this time, the charge pump 232a performs a pumping operation and the counter 233a performs a counting operation. The charge pump 233a generates the first control voltage V C1 that rises through the pumping operation, and the counter 233a counts the number of square waves of the oscillator 231a. At time t2, the counter 233a outputs …
