This design is for a 60A 2-phase Synchronous Buck Converter, incorporating the TPS40428 PMBus driverless PWM controller and the CSD95372B Smart Power Stage. The design accepts a 10V to 14V input, and provides a 1V at 60A output. The PMBus design enables programming, configuration, control, sequencing, voltage margining, Adaptive Voltage Scaling (AVS), and accurate current, voltage and temperature monitoring of high-power ASIC power supplies in Enterprise Storage/NAS/SAN, Ethernet Switches, Optical Networks, and Base Stations.
