A good PCB layout for the TPS53511RGTT should include a solid ground plane, separate analog and digital grounds, and a decoupling capacitor (e.g., 10uF) between VIN and GND. Additionally, keep the input and output capacitors close to the IC and use short, wide traces for the power paths.
Choose input capacitors with low ESR (Equivalent Series Resistance) and high ripple current rating. For output capacitors, select ones with low ESR, high capacitance, and a voltage rating that exceeds the output voltage. A good starting point is a 10uF input capacitor and a 22uF output capacitor.
The TPS53511RGTT is rated for operation from -40°C to 125°C (TJ) and -40°C to 85°C (TA) for the industrial temperature range. However, the device can be operated at higher temperatures with derating.
The output voltage of the TPS53511RGTT can be adjusted by using a resistive divider network between the VOUT pin and the GND pin. The feedback pin (FB) is connected to the center tap of the divider, and the output voltage is set by the ratio of the resistors.
The maximum input voltage for the TPS53511RGTT is 18V. Exceeding this voltage may damage the device.
