  • Patent number: 6771052
    Abstract: A multi-output DC-DC power supply has programmable operating characteristics, such as voltage levels, turn-on and off sequences, mono-phase and multi-phase operation, voltage ramp-up and ramp-offs, tracking and protection mode thresholds and action-if-fault strategies. The power supply has a DC-DC converter having an output coupled to a plurality of buck converters. Each buck converter has an output and a control input where the voltage at the output of the buck converter is determined by a duty cycle of at least one pulse width modulated signal provided at the control input of that buck converter. A programmable device has outputs coupled to the control inputs of the buck converters. The programmable device generates the pulse width modulated signals at its outputs for controlling the buck converters to provide voltages corresponding to voltages programmed in the programmable device.
