Abstract:
A voltage converter includes a high side transistor, a low side transistor coupled to the high side transistor at a switching node, and an inductor coupled to the switching node and providing an output node. A controller is provided that is coupled to the high side transistor and the low side transistor. The controller is configured to selectively turn on and off the high and low side transistors in a repeat cycle. The controller is configured to control the high and low side transistors to cause a sequence of packets of charge to be delivered to the inductor. Also included is an adaptive timer circuit coupled to the output node and the controller and configured to adaptively adjust the amount of charge in each packet based on the voltage ripple of the output node.
