Abstract
Methods and circuits for power supply arrangement and control are disclosed herein. In one embodiment, a switching regulator controller can include: (i) a first feedback circuit for sensing an output of a switching regulator to compare against a regulation reference, and to generate a control signal suitable for matching the output of the switching regulator to the regulation reference during a steady state operation of the switching regulator; and (ii) a second feedback circuit for sensing a regulation difference between the output and the regulation reference, and to generate an adjustment signal in response to the regulation difference, where the adjustment signal adjusts the control signal under transient conditions to improve transient responses of said switching regulator.
