ABSTRACT:
A monolithic digital power supply controller is disclosed for controlling the operation of a switched power supply. The controller is contained within an integrated circuit package enclosing an integrated circuit chip. A plurality of inputs are provided on the package for interfacing with the switched power supply for receiving sensed inputs therefrom. A plurality of outputs provide switch control signals for turning on and off switches in the switched power supply. An integrated digital controller on the chip receives the inputs and generates the outputs, and includes an integrated instruction based processing engine for providing a portion of the digital control of the digital controller. A memory associated with the processing engine stores instructions for the processing engine.
