Abstract: A system and method is provided for using a serial bus to communicate (either passively or actively) with a point-of-load (“POL”) regulator. Specifically, a power supply controller (“controller”) communicates with at least one POL regulators by writing and/or reading data (either synchronously or asynchronous) over a unidirectional or bi-directional serial bus. In one embodiment of the present invention, the controller is adapted to write initial-configuration data (e.g., output voltage set-point, current limit set-point, etc.) to at least one POL regulator via the serial bus. At least a portion of the initial-configuration data is then used by the POL regulator to produce a particular output. In another embodiment of the invention, each POL regulator includes at least one register for maintaining POL information, such as unique identification information, fault protection information, output voltage set-point data, current limit set-point data, etc. The controller is then adapted to monitor and retrieve this information (i.e., fault-monitoring data) via the serial bus while the POL regulators are operating.

Abstract: A system and method is provided for utilizing output-timing data to control at least one output timing parameter of a point-of-load (“POL”) regulator. Specifically, a power supply controller (“controller”) is adapted to transmit output-timing data to at least one POL regulator. In one embodiment of the present invention, each POL regulator includes an output builder, a control unit and a storage device. The control unit is adapted to store the output-timing data in the storage device. The control unit and the output builder are then adapted to produce an output having at least one output timing parameter in accordance with the output-timing data. Examples of output-timing data include sequencing data, turn-on data, turn-off data, termination data, slew-rate data, etc. For example, a POL regulator may be adapted to utilize output-timing data, or a portion thereof (e.g., slew-rate data), to generate an output having a particular slew rate. Similarly, a POL regulator may be adapted to utilize output-timing data, or a portion thereof (e.g., sequencing data, turn-on data, etc.), to determine (or calculate) a period of time to wait (e.g., delay period) before the output is generated. In other words, output-timing data can be used to produce a series of outputs in a particular order, or sequence.

Abstract: A pulse width modulation system for use in a switching power supply circuit provides high-resolution pulse width modulated signals. The pulse width modulation system is configured to receive a control signal comprising a (m+n)-bit binary word and to provide a pulse width modulated signal with a predetermined average duty cycle having a resolution of substantially 2−(m+n). The pulse width modulation system includes a timing circuit for providing 2m timing signals, a dithering circuit, and a signal generator. Upon receiving the control signal, the dithering circuit is configured to provide a modified control signal, which comprises a series of up to 2nm-bit binary words. The signal generator is configured to receive the timing signals and the modified control signal and to provide the pulse width modulated signal having a duty cycle, which, when averaged over 2n timing cycles, is approximately equal to the predetermined average duty cycle. The pulse width modulated signal is used by a switching power supply circuit to control at least one power switching device.
