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.

Abstract: A transient auxiliary converter includes: a transient auxiliary converter terminal; an inductor having a first side and a second side, the first side of the inductor coupled to the transient auxiliary converter terminal; a capacitor having a first electrode and a second electrode, the second electrode of the capacitor being coupled to ground; a first switch between the second side of the inductor and the first electrode of the capacitor; and a second switch between the second side of the inductor and ground. The first and second switches are operated in accordance with a charge mode and a transient response mode for the transient auxiliary converter. The charge mode builds up charge on the capacitor from charge at the transient auxiliary converter terminal. The transient response mode releases charge on the capacitor to the transient auxiliary converter terminal.
