Texas Instruments provides a recommended PCB layout in the TPS826721SIPR datasheet (section 10.2) and in the TPS82672EVM-001 evaluation module documentation. It's essential to follow these guidelines to minimize noise, ensure proper thermal dissipation, and optimize performance.
The output capacitor selection depends on the output voltage, output current, and desired ripple voltage. TI recommends using a low-ESR ceramic capacitor with a minimum capacitance of 10 μF and a voltage rating of at least 1.5 times the output voltage. Refer to the datasheet (section 7.3.1) for more information.
The absolute maximum input voltage rating for the TPS826721SIPR is 6.5 V. However, the recommended operating input voltage range is 2.7 V to 5.5 V. Applying voltages above 6.5 V can damage the device.
To ensure stability, follow the recommended PCB layout, use a sufficient output capacitor, and ensure the input capacitor is properly sized. Additionally, avoid using long input traces and keep the input capacitor close to the VIN pin. If oscillations occur, try adding a small ceramic capacitor (10 nF to 100 nF) between the VIN and GND pins.
The TPS826721SIPR has a thermal derating of 12.5 mW/°C above 25°C. This means that for every 1°C increase in temperature above 25°C, the maximum power dissipation decreases by 12.5 mW. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.
