This reference design provides customers with a comparison study on the usage of GaN vs SI in power supply designs. This specific design uses TPS40400 controller to drive CSD87381 for the silicon power supply and LMG1210 with EPC2111 for the GaN power supply to provide 0.8V/10A. This design compares the silicon and GaN power stages and illustrates the design tradeoffs and necessary optimizations when designing with GaN.
