ASYMMETRIC PHASE CURRENT REGULATION FOR MULTIPHASE SWITCHMODE POWER SUPPLIES
First Claim
Patent Images
1. A multiphase voltage regulator (VR), comprising:
- a first phase that is configured to generate a first phase current when the first phase is active; and
a second phase that is configured to generate a second phase current when the second phase is active, the second phase current being a predetermined fraction less than the first phase current.

Abstract
According to certain general aspects, the present embodiments relate generally to allowing phase currents of a multiphase switching power supply to be asymmetrically configured to any percentage of the total load current while maintaining excellent dynamic performance. According to certain other aspects, this allows for increased design flexibility for board area, solution cost and optimized efficiency.
