Embodiment Construction

[0019] The present invention provides a system and method for programming and / or monitoring a POL regulator using a point-of-load ("POL") control unit. In the detailed description that follows, like element numbers are used to describe like elements illustrated in one or more figures.

[0020] Figure 1 illustrates a prior art DC / DC control system 10 in which a power supply controller ("controller") 110 connects a number of external circuits ( For example, R1 / S1, R2 / S2, R3 / S3), and through many three-wire output connections (i.e., 122-126, 132-136, and 142-146) to many DC / DC converters (i.e., 120, 130 and 140) (also known as voltage regulator or POL regulator) for communication. Specifically, each six-bit parallel bus includes an enable / disable bit and five VID code bits, and each three-wire output connection includes voltage monitoring lines (i.e., 122, 132, and 142), current monitoring lines (i.e., 124, 134, and 144) and switch enable lines (ie, 126, 136, 146).

Abstract

Systems and methods for communicating with voltage regulators are disclosed. The present invention provides a method for programming and / or monitoring a POL regulator using a point-of-load ("POL") control unit. In one embodiment, a power supply controller is used 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 the memory device and uses at least a portion of the initial configuration data to generate an output. The POL control unit is further configured to store the fault monitoring data in the storage device and provide at least a part of the fault monitoring data to the controller. If a provided part violates a known parameter, the controller (or POL control unit) can respond by performing a specific action. In another embodiment, the POL regulator further includes at least one sensor circuit for generating fault monitoring data, or data usable to determine fault monitoring data. In another embodiment, initial configuration data and fault monitoring data are transmitted over a serial data bus.

Description

technical field [0001] The present invention relates to controlling a point-of-load ("POL") regulator, and more particularly, to a system and method for programming and / or monitoring a POL regulator using a POL control unit. Background technique [0002] Point-of-load ("POL") regulators, also known as voltage regulators or DC / DC converters, are commonly used with electronic circuits. This is because the voltage / current requirements of electronic circuits are often different than the available voltage or current that can be delivered in practice. For example, some electronic devices include only a single voltage input (eg, 12v), but require different voltages (eg, 3v, 5v, 9v, etc.) for the included circuitry. A common solution is to design multiple POL regulators within the device to convert a single input voltage to multiple voltage levels. [0003] Also, some electronic devices include circuitry that requires a low voltage (eg, 1v), high current (eg, 100A) power supply. ...
