Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow the guidelines in the TI application note 'TPS61161 PCB Layout Guidelines' (SLVAUH7) for optimal performance and thermal management.
The selection of the inductor depends on the output current, output voltage, and switching frequency. TI provides an inductor selection guide in the datasheet, but it's also recommended to use the TI Webench Power Designer tool to find the optimal inductor for the specific application.
The maximum junction temperature for the TPS61161DRVTG4 is 150°C. However, it's recommended to keep the junction temperature below 125°C for optimal reliability and performance.
Yes, the TPS61161DRVTG4 is rated for operation up to 125°C ambient temperature. However, it's recommended to derate the output current and voltage according to the thermal derating curve in the datasheet to ensure reliable operation.
TI provides a troubleshooting guide in the datasheet, which covers common issues such as output voltage regulation, efficiency, and thermal shutdown. Additionally, TI's Power Management Forum and E2E community provide resources and support for troubleshooting and design optimization.
