A good PCB layout for the TPS26621DRCT involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. A 4-layer PCB with a dedicated power plane is recommended.
When selecting an inductor for the TPS26621DRCT, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to choose an inductor with a saturation current rating of at least 1.5 times the maximum output current, and a DC resistance of less than 100 mΩ.
The TPS26621DRCT is rated for operation from -40°C to 125°C, but the maximum ambient temperature range depends on the specific application and the device's power dissipation. Consult the datasheet and thermal design guidelines for more information.
Yes, the TPS26621DRCT is qualified for automotive and high-reliability applications. It meets the requirements of the AEC-Q100 standard and is suitable for use in harsh environments.
To troubleshoot issues with the TPS26621DRCT, start by checking the input voltage, output voltage, and current levels. Verify that the PCB layout and component selection meet the recommended guidelines. Use an oscilloscope to check for voltage ripple, and a thermal camera to check for hotspots.
