Patent ID: 8886970

Claim:
An integrated circuit comprising: a first tile comprising a Configurable Switching Power Supply Pulse Width Modulator (CSPSPWM), a driver output terminal, a driver coupled to receive a driver input signal from the CSPSPWM and coupled to drive a driver output signal onto the driver output terminal, a supply voltage terminal VP couplable to an error amplifier of the CSPSPWM, and a configuration register, wherein configuration information stored in the configuration register determines a configuration of the CSPSPWM; a second tile comprising a terminal, circuitry coupled to the terminal of the second tile, and a configuration register, wherein configuration information stored in the configuration register determines a configuration of the circuitry, wherein the circuitry is taken from a group consisting of: a driver output circuit that outputs a signal onto the terminal of the second tile, and an amplifier circuit that receives a signal from the terminal of the second tile; a memory; and a processor adapted to access the memory and to execute instructions stored in the memory, wherein the processor is powered substantially entirely by power received from the first tile as a result of an operation of the CSPSPWM, wherein the processor is configured to write across a standardized bus to the configuration register in the first tile thereby configuring the CSPSPWM, and wherein the processor is configured to write across the standardized bus to the configuration register in the second tile thereby configuring the circuitry of the second tile.
