Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow the guidelines in the TI application note 'PCB Layout Guidelines for Switching Regulators' (SLUP220) for optimal performance and thermal management.
The selection of the inductor depends on the specific application requirements, such as the input voltage, output voltage, and output current. TI provides an inductor selection guide in the datasheet, and also recommends using the WEBENCH Power Designer tool to find suitable inductors.
The maximum junction temperature (Tj) of the BQ29311PWRG4 is 150°C. However, it's recommended to keep the junction temperature below 125°C for optimal reliability and performance.
Yes, the BQ29311PWRG4 is rated for operation up to 105°C ambient temperature. However, the device's performance and reliability may be affected at high temperatures, and it's recommended to follow the guidelines in the datasheet for high-temperature operation.
TI provides a troubleshooting guide in the datasheet, which covers common issues such as output voltage errors, oscillations, and overcurrent protection. Additionally, TI's support team and online forums can provide further assistance.
