Abstract: Disclosed examples include self-biased DLL circuits to generate a bias current signal proportional to a repetition frequency of a first signal representing continuous switching or discontinued switching operation of the DC-DC converter. The DLL circuit includes a monostable multivibrator to provide a pulse output signal in response to an edge of the first signal with a pulse duration set by a control current signal, a phase detector to provide output signals according to a phase difference between an edge of the pulse output signal and the first signal, and an output circuit to provide an output signal according to the phase detector output signals and according to an offset signal, to provide the bias current signal according to the output signal, and to provide the control current signal according to the output signal.

Abstract: A timing regulation circuit includes a fixed and tunable timer. A current source generates a source current I1 proportional to an inductor voltage ΔV1 of a DC-DC converter during an energizing phase and a current source generates a sink current I2 proportional to inductor voltage ΔV2 during a de-energizing phase. The fixed timer controls a first switch in series with I1 or I2 and the tunable timer controls a balancing switch in series with the other current. I1 or I2 is coupled by the first switch and the other current is coupled by the balancing switch to a common capacitor that provides a regulation voltage to the tunable timer which outputs a regulated duration (Tregulated) for an energizing or de-energizing phase. When Tregulated closes the balancing switch the common capacitor provides a predicted current returning inductor current to a starting value when all phases finish for providing a volt-second balance.

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 multi-phase power converter includes a plurality of power channels arranged in parallel to drive an output of the power converter, and a channel selection circuit. Each of the power channels includes a driver, a feedback control circuit coupled to an output of the driver, and a comparator coupled to the feedback control circuit. The channel selection circuit is coupled to the feedback control circuit of each of the power channels. The channel control circuit is configured to: select a different specific one of the power channels to activate in each of a plurality of phases, and introduce an offset voltage into each of the feedback control circuits, except the feedback control circuit of the specific one of the power channels. The feedback control circuit is configured to apply the offset to bias driver output feedback voltage away from a threshold voltage at which the power channel is activated.

Abstract: A DC-DC converter includes a first differential voltage sensor to detect a first inductor current by sensing a first differential voltage across a first power stage of the DC-DC converter. A second differential voltage sensor detects a second inductor current by sensing a second differential voltage across a second power stage of the DC-DC converter. An integrator stage combines the first differential voltage from the first power stage and the second differential voltage from the second power stage to generate a compensation signal to adjust current balancing for the DC-DC converter.
