    摘要: A digital controller for controlling the operation of a DC-DC switching converter is disclosed. A digital feedback control system is provided for receiving an analog input voltage representing the output of the switching converter and digitally processing the analog input voltage by comparing it to a reference voltage and then determining analog drive signals to control the operation of the switching converter to provide a regulated output. The digital feedback control system operates in accordance with predetermined operating parametrics. The digital feedback control system also has monitoring inputs and control inputs. A microcontroller monitors the operation of the digital feedback control system and is able to change the operating parametrics under certain predetermined conditions.

    摘要: 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.

    摘要: A system for monitoring interrupts to a processor includes a multiplexer having a plurality of inputs connected to receive various analog inputs. The multiplexer further has an output which is programmably connected to one of the plurality of inputs responsive to a control signal. An analog to digital converter is connected to the output of the multiplexer for converting an analog signal at the output to a digital signal. An auto-scan block generates the control signal provided to the multiplexer. The control signal selects ones of the plurality of inputs of the multiplexer for connection to the output in a programmably defined order.
