Current balancing for voltage regulator having inputs from multiple power supplies |
摘要 |
A voltage regulator is provided. The voltage regulator comprises a first voltage-controlled current regulator having a first power input and at least one additional voltage-controlled current regulator having at least one other power input. The first and the at least one additional voltage-controlled current regulators have first and second current paths, respectively, and a common output node. The voltage regulator also includes an error amplifier that is responsive to the common output node. The error amplifier further has an output. The output of the error amplifier provides a common feedback signal to the first and the at least one additional voltage-controlled current regulators so as to establish selected currents drawn by the first and the at least one other power inputs and provided to the common output node.
