Abstract
A mixed signal controller (MSC) is used to vary the rise times and trim voltages used on a printed circuit (PC) board. The use of an MSC reduces the number of components on a PC board which may reduce the complexity, cost and size of the PC board.
Claims24
A device for controlling the distribution of power on a printed circuit board comprising:
- a program code section operable to control the voltage rise time and trim voltage level of one or more voltages generated by one or more direct current (DC)-to-direct current (DC) converters;
- and
- a program code section operable to control the selection of one or more electronic switches, each selected switch operable to receive one or more of the generated, controlled voltages.
A device for distributing controlled, direct current (DC) voltages to one or more portions of a printed circuit board comprising:
- one or more electronic switches operable to receive a selection signal and one or more controlled voltages and to distribute received, controlled voltages to a portion of a printed circuit board upon receipt of the selection signal.
A device for generating one or more controlled, direct current (DC) voltages for use by a printed circuit board comprising:
- one or more DC-to-DC converters, each converter operable to receive a first DC voltage and convert it to a second DC voltage in accordance with a received voltage control signal and further operable to supply the second DC voltage to one or more electronic switches.
A method for controlling the distribution of power on a printed circuit board comprising:
- controlling the voltage rise time and trim voltage level of one or more voltages generated by one or more direct current (DC)-to-direct current (DC) converters;
- and
- controlling the selection of one or more electronic switches, each selected switch operable to receive one or more of the generated, controlled voltages.
