Texas Instruments bq25758EVM Controller Evaluation Module (EVM)

Texas Instruments bq25758EVM Controller Evaluation Module (EVM) is an evaluation system for the bq25758 IC. The bq25758 IC is a buck-boost controller with a wide input range of 4.2V to 60V, a wide output voltage range of up to 60V, bi-directional capabilities, and the IC supports the full range of USB PD 3.1 EPR from 5V to 48V at 240W. The device offers high-efficiency DC/DC conversion over a wide voltage range. The device integrates all the loop compensation for the buck-boost converter, providing a high-density method with ease of use.

The Texas Instruments bq25758EVM does not include the EV2400 or USB2ANY interface device and does not provide any electrical isolation for the digital interfaces. EV2400 or USB2ANY must be ordered separately to evaluate the bq25758EVM, and electrical safety considerations must be considered when interfacing between the PC and the evaluation module board. When interfacing the evaluation module to the PC through digital interfaces, digital isolators with an isolation boundary are recommended.
