TPS78228DDCT Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS78228DDCT involves placing the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. TI provides a recommended PCB layout in the datasheet and application notes.
  • To ensure stability, follow the recommended component values and PCB layout guidelines. Additionally, ensure that the output capacitor has a low equivalent series resistance (ESR) and is placed close to the device. A minimum output capacitance of 10uF is recommended.
  • The TPS78228DDCT has an absolute maximum input voltage rating of 6.5V. However, the recommended maximum operating input voltage is 5.5V to ensure reliable operation and minimize the risk of damage.
  • The TPS78228DDCT is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. Ensure that the device is properly heatsinked and follow the recommended thermal design guidelines.
  • The output voltage of the TPS78228DDCT is determined by the resistor divider network connected to the FB pin. Use the formula: Vout = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
