High-Density 12Vin: 1.2Vout: 60A POL Reference Design with Stacked TPS546C20A PMBus DCDC Converters
Description
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. PMP20292 shows a high current two phase application with inductors on top of control ICs for smaller footprint and two on board dynamic loads. The Test Report shows the loss sharing between the two power stages and transient load response with each of the two on board dynamic loads.
Features
- Complete high current 2 phase DC/DC converter with all the advantages of phase interleaving using only two of the single phase partsFixed frequency voltage mode control allows for user selection of switching frequency and synchronization to an external clockInductors on top of controllers for small overall footprintRich test interface including a self contained high speed dynamic test load and a Signal Generator driven dynamic test loadSchematic: BOM: layout and Test Report focusing on efficiency & load / thermal sharing and load dynamics with each of the on board test loads
