TPS23841PAPR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the high-current paths short and wide, and use vias to connect the power planes to the device pins.
  • Follow the recommended power-up sequence: VCC, then EN, then VIN. Ensure the input voltage is within the recommended range, and the EN pin is pulled high to enable the device.
  • The maximum current rating is 1.5 A. Calculate power dissipation using the formula: Pd = (VIN - VOUT) x IOUT. Ensure the device is properly heatsinked to prevent overheating.
  • Use the FB pin to set the output voltage. The device supports output voltages from 0.9 V to 3.3 V. However, the output voltage range is limited by the input voltage and the internal voltage drop.
  • The device has a thermal shutdown at 150°C. Ensure good airflow, use a heatsink, and keep the device away from other heat sources. Monitor the junction temperature and adjust the design accordingly.
