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.
Features
- Complete high current 2 phase DC/DC converter with all the advantages of phase interleaving using only two of the single phase parts
- Fixed frequency voltage mode control allows for user selection of switching frequency and synchronization to an external clock
- Output voltage, current limit and fault thresholds / responses can be adjusted "on the fly" thru the PMBus interface
- Rich test interface including PMBus socket, and high speed dynamic test load
- Schematic, BOM, layout and Test Report focusing on thermal performance & load dynamics
