Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines for switching regulator layout, such as keeping the input and output capacitors close to the IC, and using a solid ground plane to reduce noise and EMI.
To ensure stability, make sure to follow the recommended component values and layout, and also consider the output capacitor's ESR (Equivalent Series Resistance) and ESL (Equivalent Series Inductance) when selecting the output capacitor. Additionally, adding a small ceramic capacitor (e.g. 10nF) between the VOUT and GND pins can help to improve stability.
The maximum input voltage rating for the TPS12110AQDGXRQ1 is 18V, but it's recommended to operate the device within the recommended input voltage range of 6.5V to 14V for optimal performance and reliability.
The TPS12110AQDGXRQ1 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation. Additionally, consider the thermal design and heat sinking of the PCB to ensure the device operates within its recommended temperature range.
To troubleshoot issues, start by verifying the input voltage, output voltage, and output current are within the recommended specifications. Check the PCB layout and component values to ensure they match the recommended design. Use an oscilloscope to measure the output voltage and current waveforms, and check for any signs of oscillation or instability. If the issue persists, consider consulting the Texas Instruments support resources or seeking assistance from a qualified engineer.
