TPS78633DCQ Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS78633DCQ involves placing the input and output capacitors close to the device, using a solid ground plane, and keeping the input and output traces separate to minimize noise coupling. TI provides a recommended PCB layout in the datasheet and application notes.
  • To ensure stability, make sure to follow the recommended PCB layout, use a sufficient output capacitor (at least 10uF), and add a small ceramic capacitor (around 10nF) between the output and ground. Additionally, ensure the input voltage is within the recommended range and the device is not overheating.
  • The TPS78633DCQ can handle input voltages up to 15V, but it's recommended to keep the input voltage below 12V for optimal performance and to prevent overheating.
  • The TPS78633DCQ is rated for operation up to 125°C, but its performance may degrade at high temperatures. Ensure proper heat sinking and thermal management to prevent overheating, and consider using a heat sink or thermal pad if operating in high-temperature environments.
  • The output voltage of the TPS78633DCQ is determined by the resistor divider network (R1 and R2) connected to the FB pin. Use the formula: Vout = 0.8V x (1 + R2/R1) to calculate the output voltage.
