TPS40428RHAT Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS40428RHAT involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. TI provides a recommended layout in the datasheet and in application notes.
  • Choose input capacitors with low ESR and high ripple current rating. For output capacitors, choose ones with low ESR and high capacitance. The datasheet provides guidelines for capacitor selection, and TI's capacitor selection tool can also be used.
  • The TPS40428RHAT is rated for operation from -40°C to 125°C. However, the maximum ambient temperature range depends on the specific application and the device's power dissipation. Consult the datasheet and thermal design guidelines for more information.
  • The TPS40428RHAT has a built-in overcurrent protection feature. To implement it, connect a sense resistor in series with the output, and connect the sense pin to the sense resistor. The device will limit the output current to the programmed value.
  • Yes, the TPS40428RHAT is AEC-Q100 qualified and suitable for automotive and high-reliability applications. However, additional testing and validation may be required for specific applications.
