Description for the BQ25720EVM
The BQ25720 evaluation module (EVM) is a SMBus controlled NVDC (narrow voltage DC) buck boost charge controller with N-channel MOSFET selector and current monitoring. The input voltage range, for the buck converter, is between 3.5 V and 26 V, with a programmable output of 1 to 4 cells and a charge output current range of 64 mA to 8 A. This EVM doesn’t include the EV2400 interface device; this will have to be ordered separately to evaluate the BQ25720EVM.
