Abstract: A voltage converter system includes a switch adapted to be coupled to an inductor, and configured to switch between first and second states responsive to a control signal. Calibration circuitry is configured to generate a calibration signal, including setting the calibration signal to a particular value for a particular time responsive to a transient from a first load condition of the voltage converter system to a second load condition of the voltage converter system. Control circuitry is coupled to the calibration circuitry and configured to generate the control signal based on a combination of a feedback voltage, a reference voltage, the calibration signal, and a periodic signal.

Abstract: A voltage converter system includes a switch configured to switch between first and second states responsive to a first control signal. Timer circuitry is configured to generate a timing signal representing a duration of the first state based on input and output voltages of the voltage converter system. Control logic is coupled to the switch and the timer circuitry, and configured to generate the first control signal based on a second control signal. The second control signal is based on a feedback voltage and a reference voltage. Timer control circuitry is coupled to the control logic and the timer circuitry, and configured to: detect a phase difference between the first control signal and the second control signal; and adjust the timer circuitry to change the duration based on the phase difference.

Abstract: USB charger apparatus and chargeable electronic devices are presented in which the device and charger use USB cable data lines to establish a bidirectional communications connection, and the charger provides charger capability information to a master controller of the electronic device via the communications connection. The device controller preferentially selects a fastest charging match between the charger capability information and device charging capability information, and sends configuration information through the communications connection to set the power supply level of the charger. The charger communicates power supply status information to the electronic device, and the device can reconfigure the charger power supply level accordingly.
