The TPS546C20A provides a single IC for both control & the synchronous power stage for high current DC/DC applications and allows doubling of the current capability with use of two of the same part. Multi-phase also allows output ripple cancellation and effective higher bandwidth control for a given switching frequency. PMP20071 shows a high current two phase application. The Test Report show the loss sharing between the two power stages: output ripple reduction and improved dynamic response due to the two phases.
