Abstract:
1. A DC-to-DC converter comprising: first and second transistors each driven by pulse-width modulated (PWM) pulses and each having first and second terminals and a control terminal, wherein the first terminal of the first transistor is connected to a supply voltage, the second terminal of the first transistor and the first terminal of the second transistor are connected to a node, the second terminal of the second transistor is connected to ground, and the node is connected to an inductance that is connected in series to a load; a first timing module that determines a first time difference between a first edge of a first signal at the node and a first edge of a second signal at the control terminal of the first transistor, wherein the first edge of the second signal corresponds to a first edge of one of the PWM pulses; a second timing module that determines a second time difference between a second edge of the first signal at the node and a second edge of the second signal at the control terminal of the first transistor, wherein the second edge of the second signal corresponds to a second edge of the one of the PWM pulses; a delay module that delays the first edge of the second signal at the control terminal of the first transistor based on the first time difference and that delays the second edge of the second signal at the control terminal of the first transistor based on the second time difference; and a charge pump that outputs a voltage, wherein the delay module delays an edge of one of the PWM pulses based on an amount of change in the voltage output by the charge pump.
