Title:
CHARGE PUMP CIRCUIT AND HALF-BRIDGE DRIVER CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2024/065405
Kind Code:
A1
Abstract:
The present application provides a charge pump circuit and a half-bridge driver circuit. The charge pump circuit comprises: an input voltage switch circuit which is connected to an input voltage and a charge pump control signal and outputs the input voltage under the control of the charge pump control signal; a regulation voltage generation circuit which is connected to the input voltage and outputs a regulation voltage; a regulation voltage loading control circuit which is connected to both the regulation voltage generation circuit and the charge pump control signal and loads the regulation voltage under the control of the charge pump control signal; and a charging circuit which is connected to all of the input voltage switch circuit, the regulation voltage generation circuit, and the regulation voltage loading control circuit and outputs an output voltage, wherein the output voltage = the input voltage + the regulation voltage. According to the charge pump circuit and the half-bridge driver circuit of the present application, the charge pump circuit is formed by discrete components, the structure is simple, and the cost is low; moreover, parameters can be adjusted according to actual needs, and peripheral applications are flexible and convenient.
