Abstract: A current sensing circuit comprises a power device adapted to conduct a bidirectional current between first and second terminals thereof, first and second sensing devices operatively coupled to the power device, a sense amplifier providing first and second voltages to the first and second sensing devices, and a gate drive device providing activating signals to the power switching device and the first and second sensing devices. The first and second sensing devices each has an active area that is substantially identical and significantly smaller than a corresponding active area of the power switching device. The sense amplifier measures the voltage of the first sensing device and maintains the voltage on the second sensing device at the same level as the first sensing device by injecting an additional current into the second sensing device. The sense amplifier further provides an output signal proportional to the bidirectional current. The first and second sensing devices have k times higher resistance than a corresponding resistance of the power device when in an active state.

Abstract: A switched mode voltage regulator has a digital control system that includes dual digital control loops. The voltage regulator comprises at least one power switch adapted to convey power between respective input and output terminals of the voltage regulator and a digital controller adapted to control operation of the power switches responsive to an output of the voltage regulator. The digital controller further comprises dual digital control loops in which a first control loop provides high speed with lower regulation accuracy and a second control loop has high accuracy with lower speed. Thus, the digital control system provides the advantages of both high speed and high regulation accuracy.

Abstract: A system and method is provided for determining a voltage output of a programmable power converter based on programming voltage data received from one of a variety of alternate sources. Specifically, in one embodiment of the present invention, a control unit is adapted to monitor a digital data serial interface, a digital data parallel interface, and an analog data interface to determine whether programming voltage data has been received. If programming voltage data has been received, the data is used to determine an output voltage for the programmable power converter. If more than one set of programming voltage data has been received, a determination is made as to which set of data takes priority. The selected set of data is then used to determine an output voltage for the programmable power converter.

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 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 current sensor is provided that employs a primary winding that carries the current to be measured, and a secondary winding that controls the flux inside the magnetic core, provides a sample of the primary current, and also helps to control the flux at small primary currents and to saturate the transformer. An auxiliary winding is optionally used to control the flux in order to simplify control of the sensor. By periodically applying a certain voltage at the secondary winding, the transformer core is forced out of saturation, and a sample of the primary current is taken by a sensing circuit that may include a sample-and-hold circuit and an analog-to-digital converter. A control circuit is employed to control the currents flowing in the secondary winding and optional auxiliary winding and to manage the sensing circuit.

A second digital circuit is adapted to provide a counter that combines the first function value f(ek) with a previous counter state Nk to provide a next counter state Nk+1, the next counter state Nk+1 being applied as an input to the digital-to-analog converter. A third digital circuit is adapted to scale the previous counter state Nk by a factor M and combine the scaled counter state M·Nk with the error signal ek to provide a digital output value Dk representing the input voltage Vi.
