BQ2577xGEVM Evaluation Module
Description
The BQ2577xGEVM is a complete high-power
high-efficiency battery charger using SMBus or I
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 2–5
cells and a charge current range of 0A to 16.3A.
This BQ2577xGEVM allows the users 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).
