ABSTRACT:
A regulator with output current sharing including an output node and multiple converters. Each converter includes a PWM controller and switch circuit, an inductor, and an RC circuit. Each PWM controller and switch circuit receives a corresponding rail voltage and has a phase node and a regulation feedback input. Each inductor has a first end coupled to the output node and a second end coupled to a corresponding phase node. The RC circuit is coupled across the inductor and has an intermediate phase sense node coupled to a corresponding regulation feedback input. Each RC circuit may include an RC filter coupled across an inductor with an intermediate node and a feedback circuit coupled between the intermediate node and a regulation feedback input. The RC circuits may be configured to program a relative power distribution between the rail voltages to the shared output.
