Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines for high-current switching regulators, such as keeping the power traces short and wide, and using a solid ground plane to reduce EMI.
The datasheet provides a list of recommended inductors, but you can also use the inductor selection guide provided by Texas Instruments to select the right inductor based on your specific application requirements, such as output current, switching frequency, and inductor core material.
The BQ294708DSGT is rated for operation up to 105°C ambient temperature, but it's recommended to derate the device's performance at higher temperatures to ensure reliable operation.
The BQ294708DSGT is designed to meet the requirements of automotive and industrial applications, which often involve high-vibration environments. However, it's recommended to follow proper PCB mounting and assembly techniques to ensure the device's reliability in such environments.
Common issues with output voltage regulation can be caused by incorrect component selection, poor PCB layout, or incorrect configuration of the device's pins. Use an oscilloscope to measure the output voltage and current, and refer to the datasheet and application notes for troubleshooting guidelines.
