Embodiment Construction

[0015] The following description is of an exemplary nature only and is not intended to limit the invention and its application and use. For the sake of clarity, the same reference numerals are used to designate similar elements in the drawings. As used herein, the phrase "at least one of A, B, and C" shall be constructed to mean a logical (A or B or C) using an exclusive logical "or". It should be understood that steps within a method may be executed in different order without altering the principles of the present disclosure.

[0016] The term "module" as used herein may be: part or all of an application specific integrated circuit (ASIC); an electronic circuit; a combinational logic circuit; a field programmable gate array (FPGA); a processor (shared, dedicated) that executes code or group); other suitable components that provide the described functionality; or a combination of all or a portion of the above, such as a system-on-a-chip. The term "module" also includes memor...

Abstract

A current share system for providing current to a load includes a first power supply module that controls a first voltage converter to provide a first current to the load, transmits synchronization information using a first pin, and transmits at least one second type of information using the first pin, a second power supply module receives the synchronization information at a second pin, receives the at least one second type of information at the second pin, and controls a second voltage converter to provide a second current to the load based on the synchronization information and the at least one second type of information.

Description

technical field [0001] The present invention relates to a power control system, and more particularly, to a system and method for current sharing between DC-DC converters. Background technique [0002] The background description provided herein is for the purpose of generally presenting the background of the invention only. Certain work of the inventors named herein (that is, work that has been described in this Background section) and content of the specification with respect to certain prior art that is not prior to the filing date, whether explicit or None of the implied approaches are considered to be prior art with respect to the present invention. [0003] The power supply outputs a preset voltage for powering one or more components. For example, the preset voltages described above may power one or more components of an integrated circuit (IC). However, in some cases a voltage less than the preset voltage value may be sufficient. The lower voltage can be obtained f...
