Abstract: The present application is directed at pin programming od controllers for power converters and provides for the programming of a plurality of different controller parameters using a single programming resistor. The value of the programming resistor is used as a pointer to select a table storing a plurality of different settings for the controller.
Abstract: The present application relates to controllers using current mode control to control the operation of switching power supplies such as DC-DC converters. The application provides an inductor current.
Abstract: The present application relates to power converters, particularly switch mode power converters sharing a load in which the converters are operated to share stresses between them. The application provides a controller (108) in which a stress share control loop (108a, 108b) is provided to ensure the associated converter is operating at an average stress. The stress share control loop has a proportional and an integral term in its feedback path. The integral term may be enabled or disabled. In use, the integral term is enabled in all but one controller.

Abstract: Methods and circuits for power supply arrangement and control are disclosed herein. More specifically the application relates to a control method and a controller for a DC-to-DC converter, such as a synchronous Buck converter, which implements a transient detection scheme together with response generation to allow the converter to recover from a positive and/or negative load current step in the robust way, with low undershoot/overshoot at the output voltage. The control method may be implemented by either an analog or a digital circuit. The controller may be integrated with existing controller schemes (such as voltage-mode controllers) to provide superior dynamic performance during large-signal transient conditions while providing stable operation during steady state conditions. The methods and circuits provided herein are applicable to Buck converters and Buck-derived converters such as forward, push-pull, half-bridge, and full-bridge converters.
Abstract: The present application provides a tunable compensator providing a control signal to control a switch in a power supply. A measurement is taken of the level of activity of the control signal. This measurement is used to introduce a bias into a tuner tuning the compensator when the amount of activity in the control signal drops.
