摘要： A system and method is provided for utilizing output-timing data to control at least one output timing parameter of a point-of-load (nullPOLnull) regulator. Specifically, a power supply controller (nullcontrollernull) 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.

Specifically, in one embodiment of the present invention, a power supply controller is adapted to provide initial-configuration data to at least one POL regulator. A POL control unit (located within the POL regulator) then stores at least a portion of the initial-configuration data in a storage device and uses at least a portion of the initial-configuration data to produce an output. The POL control unit is further adapted to store fault-monitoring data in the storage device and provide at least a portion of the fault-monitoring data to the controller. If the provided portion violates a known parameter, the controller (or POL control unit) may respond by perform a particular action (e.g., disable the POL regulator, etc.). In another embodiment of the present invention, the POL regulator further includes at least one sensor circuit adapted to produce fault monitoring data, or data that can be used to determine the fault-monitoring data. In another embodiment of the invention, the initial-configuration data and the fault-monitoring data are transmitted over a serial data bus.

摘要： A mounting structure for a semiconductor die that reduces die attach strain within the die attach material without sacrificing the electrical and thermal characteristics of the package. In one embodiment, the mounting structure comprises a die attach metallization layer, a solder mask, and a layer of die attach material. The solder mask forms a solder pattern over the top surface of the die attach metallization layer. The solder pattern covers a portion of the die attach metallization layer to create multiple exposed areas of the die attach metallization layer. Each exposed area is separated by the solder mask and is located under the semiconductor die when the semiconductor die is secured to the mounting structure. A layer of die attach material covers the solder pattern and fills in each one of the exposed areas to form a semiconductor die mounting surface. In another embodiment, the die attach metallization layer is divided into multiple, spaced-apart die attach pads that are electrically coupled together. A layer of die attach material covers a portion of each die attach pad and fills in the space between each die attach pad to form a semiconductor die mounting surface. A method of manufacturing the mounting structure is also disclosed.

摘要： A system and method is provided for using a serial bus to communicate (either passively or actively) with a point-of-load (nullPOLnull) regulator. Specifically, a power supply controller (nullcontrollernull) 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.

摘要： A power supply comprises at least one power switch adapted to convey power between input and output terminals of the power supply, and a digital controller adapted to control operation of the at least one power switch responsive to an output measurement of the power supply. The digital controller comprises an analog-to-digital converter providing a digital error signal representing a voltage difference between the output measurement and a reference value, a digital filter providing a digital control output based on a sum of previous error signals and previous control outputs, an error controller adapted to modify operation of the digital filter upon an error condition, and a digital pulse width modulator providing a control signal to the power switch having a pulse width corresponding to the digital control output. The analog-to-digital converter further comprises a windowed flash analog-to-digital converter having a transfer function defining a relationship between the voltage difference and corresponding digital values. The transfer function provides a substantially linear region at a center of a corresponding error window, including a first step size in the center of the error window and at least one other step size in a peripheral region of the error window that is larger than the first step size. The first step size and the other step sizes may each reflect a linear relationship between the voltage difference and the corresponding digital values. Alternatively, the first step size reflects a linear relationship between the voltage difference and the corresponding digital values, and the other step sizes each reflect a non-linear relationship between the voltage difference and the corresponding digital values.

摘要： A system and method for providing interleaving point-of-load (POL) regulators such that each regulator's switching cycle is phase displaced with respect to those of other POL regulators in the array is disclosed. As a result, the aggregate input and/or output reflected ripple and noise of the input, output, or both is reduced. Each regulator in the array is associated with an unique address. A serial data-line writes the phase spacing programmed to each addressable POL regulator in the array. The present invention permits phase displacement of POL regulators without limitation to the input and output voltages of each of the regulators in the array. The array of POL regulators may also operate in a phase displaced mode with only a single control line. The need for separate controllers and multiple control lines is thereby eliminated.
