The BQ2577xGEVM is a complete high-power high-efficiency battery charger using SMBus or I2C-controlled NVDC dual-phase buck boost charge controller BQ2577xG. The EVM drives GAN FETs for high efficiency. The input voltage range is from 3.5V to 40V, with a programmable output of 2 to 5 cells and a charge current range of 0A to 16.3A. This BQ2577xGEVM allows the user to evaluate the function and performance of the BQ2577xG with step-by-step instructions. The BQ2577xGEVM also serves as a reference design with complete schematic, layout and bill of materials (BOM).
