CROSS-COUPLED CHARGE PUMP FOR DRIVING A BOOTSTRAP SWITCH

This abstract first appeared for US patent application 20250112542 titled 'CROSS-COUPLED CHARGE PUMP FOR DRIVING A BOOTSTRAP SWITCH

Original Abstract Submitted

according to an embodiment, a bootstrap drive circuit for driving a bootstrap switch in a dc-dc converter is proposed. the bootstrap drive circuit includes a non-overlapping circuit, a first and a second capacitor, and a first and a second n-channel transistor. the non-overlapping circuit is configured to receive an input signal, the input signal being a function of a pulse width modulated (pwm) signal, wherein the input signal and the pwm signal are characterized by a first logic level, generate a first control signal from the input signal at a first output terminal of the non-overlapping circuit, the first control signal having the first logic level, and generate a second control signal from the input signal at a second output terminal of the non-overlapping circuit, the second control signal being characterized by a second logic level different from the first logic level.
