TPS79901DDCRG4 Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS79901DDCRG4 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, and make sure the output capacitor is sufficient to filter out high-frequency noise. Additionally, adding a small ceramic capacitor (e.g., 10nF) between the EN pin and GND can help improve stability.
  • The TPS79901DDCRG4 can handle input voltages up to 5.5V, but it's recommended to keep the input voltage below 5V to ensure reliable operation and minimize power consumption.
  • The TPS79901DDCRG4 is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's essential to consider the device's thermal characteristics and ensure proper heat dissipation in high-temperature applications.
  • The output voltage of the TPS79901DDCRG4 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.
