Abstract: Disclosed examples include isolated dual active bridge (DAB) DC to DC converters with first and second bridge circuits, a transformer with a sense coil, and a secondary side control circuit to provide secondary side switching control signals to regulate an output voltage or current signal by controlling a phase shift angle between switching transitions of the secondary side switching control signals and switching transitions of a secondary side clock signal, where the secondary side control circuit includes a clock recovery circuit to synchronize the secondary side clock signal to transitions in a sense coil voltage signal of the sense coil.

Abstract: Disclosed examples include isolated load switch driver circuits to drive a load, including an impedance circuit that receives a digital input voltage signal from a signal source, and selectively allows a current signal to flow from the signal source to charge a buffer capacitor. An impedance control circuit controls the impedance circuit to limit the current signal in response to the buffer capacitor reaching a first threshold voltage, and an output circuit provides an output isolated from the digital input voltage signal to switch the load. A signaling circuit selectively enables the output circuit to draw power from the buffer capacitor in response to the voltage of the buffer capacitor reaching the first threshold voltage.

Abstract: A switched voltage converter may be controlled with load current feedforward control loop in addition to an output voltage feedback loop. The converter includes a first switch device that is controlled to open and close at a selected switching rate with a selected duty cycle. The first switch device is coupled in series with an inductor and conducts current through the inductor while the first switch is closed. A second switch device conducts current from the inductor to an output capacitor and to load while the first switch is open to produce an output voltage and a resulting load current through the load. The load current is measured in a continuous manner and a load current feedforward control signal is generated that is representative of the load current. The switch rate and/or duty cycle of the first switch is adjusted in response to the load current feedforward control signal.

Abstract: A modulation device may include a variable burst regulator and a current-driven clock generator. The modulation device may include a first output terminal configured to provide a modulated voltage for an operating frequency over a modulation period. The current-driven clock generator may include a second input terminal configured to receive a buffered version of the modulated voltage. The current-driven clock generator may include a second output terminal configured to provide a modulated current during the modulation period. The operating frequency may be proportional to the modulated current. The operating frequency may control the operating frequency over the modulation period.
