Patent abstract
A method for a DC to DC converter with a pseudo constant switching frequency is disclosed herein. For example, some embodiments provide a DC to DC converter having a switch connected to a switching node to control a voltage of the switching node, and a switching controller that is adapted to turn on and off the switch at a substantially constant frequency based at least in part on the voltage of the switching node. The switching controller includes a modulator connected to a control electrode of the switch and that is adapted to actuate and deactuate the switch, and a first timer that is connected to the switching node and to the modulator. The first timer uses the voltage of the switching node to determine an on-time for the switch.
