GS-EVB-AUD-SMPS2-GS

Gen2 GaN Switched-Mode Power Supply Evaluation Board

This Switched-Mode Power Supply (SMPS) evaluation board provides the basis for a complete LLC Power Supply design, with Power Factor Correction (PFC). Controlled by advanced digital control methods coupled with 650V GaN enhancement mode E-HEMTs, the SMPS includes all required components and subsystems for a complete and compliant high-voltage power supply. Power can be easily scaled by redesigning the magnetic components and providing proper heatsinking and thermal management.
