    摘要: A DC-DC digital pulse width modulated power supply is disclosed for generating a DC regulated output voltage. A digital control node has a digital control voltage disposed thereon for controlling the operation of the supply, wherein the digital control voltage has a substantially zero voltage when the output voltage of the supply is at a desired regulation, the digital control voltage having a resolution defined by a least significant bit (LSB). An input node receives a DC analog reference voltage defining the output voltage of the supply. A difference device determines the difference between the analog reference voltage and the output voltage to generate said digital control voltage. An LSB variation device varies the size of the LSB without varying the value of the digital control voltage for a substantially zero difference between the analog reference voltage and the output voltage.

    摘要: A 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.
