This reference design uses four TPS546D24A converters with integrated MOSFETs to support a full load of 160A at a 0.9V output. The system operates at a switching frequency of 650 kHz and has a PMBus interface that can be used to configure key converter parameters, including internal compensation. The detailed test report includes efficiency, thermal, stability, and load transient results.
