Abstract: A voltage regulation circuit includes a switching output terminal, a high-side output transistor, a low-side output transistor, a high-side replica transistor, a low-side replica transistor, and a comparator circuit. The high-side output transistor is configured to drive the switching output terminal. The low-side output transistor is configured to drive the switching output terminal. The high-side replica transistor is coupled to the high-side output transistor. The low-side replica transistor is coupled to the high-side replica transistor and the low-side output transistor. The comparator circuit is coupled to the high-side replica transistor and the low-side replica transistor, and is configured to compare a signal received from both the high-side replica transistor and the low-side replica transistor to a ramp signal.

Abstract: A DC-to-DC voltage converter includes a converter input for receiving a DC voltage. A first switch is coupled between the input and a first node. A second switch is coupled between the first node and a ground. An inductor is coupled between the first node and a converter output. A capacitor is coupled between the converter output and ground. An output voltage synthesizer is coupled to the converter input and the converter output for synthesizing the voltage at the first node and for generating a control signal for at least one of the first switch and the second switch in response to the voltages at the converter input and the converter output.

Abstract: A controller for a DC-DC converter includes a state machine and a plurality of drivers for controlling switches in the DC-DC converter, where each state in the state machine determines a state of the drivers, and a plurality of timers, where each state in the state machine, other than a passive state, has an associated timer for the state of the drivers.
