80V Optimized GaN Half-Bridge Power Stage
The uP9804EVM is designed to evaluate the uP9804 GaN half-bridge power stage with uP9530 multi-phase controller. The EVM reflects a 350W, 48V to 12V non-isolated buck converter design in a 40mm x 30mm board area whilst achieving ~ 97% efficiency. The uP9804 integrates a high speed GaN driver with adjustable dead time and half-bridge GaN power stage using enhancement-mode GaNFETs.
The uP9530 multi-phase controller has output current detection to support dynamic phase selection for current balance.
