Power Supply Unit with Dynamically Configurable Power Distribution

A method for dynamically allocating power for different output rails, comprising:

• by a power supply unit (PSU):
• receiving an input power signal;
• providing a first portion of the input power signal to a first load circuit and a second portion of the input power signal to a second load circuit;
• outputting a first output rail using the first load circuit and outputting a second output rail using the second load circuit;
• receiving a control signal;
• and
• dynamically adjusting, using a control circuit, power configurations of the first load circuit and the second load circuit, wherein a given power configuration specifies a given output power rating of a given output rail of a given load circuit.

An electronic device, comprising:

• a power supply unit (PSU), wherein the PSU comprises:
• an input node configured to electrically couple to an input power signal;
• a bridge circuit electrically coupled to the input node and a primary winding of a transformer;
• the transformer having the primary winding, a first secondary winding and a second secondary winding;
• a first load circuit configured to provide a first output rail and a second load circuit configured to provide a second output rail, wherein the first load circuit is electrically coupled to the first secondary winding and the second load circuit is electrically coupled to the second secondary winding;
• a control node configured to receive a control signal;
• and
• a control circuit, electrically coupled to the control node, the first load circuit and the second load circuit, configured to dynamically adjust power configurations of the first load circuit and the second load circuit, wherein a given power configuration specifies a given output power rating of a given output rail of a given load circuit.
