TPS40345DRCR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS40345DRCR 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 application notes.
  • Choose input capacitors with low ESR and high ripple current rating. For output capacitors, select ones with low ESR and high capacitance. TI recommends using ceramic or polymer capacitors with X5R or X7R dielectrics. Refer to the datasheet for specific recommendations.
  • The TPS40345DRCR is rated for operation from -40°C to 125°C. However, the maximum ambient temperature range depends on the specific application and thermal design. Consult the datasheet and thermal design guidelines for more information.
  • The TPS40345DRCR has a built-in overcurrent protection feature. To implement it, connect a sense resistor (Rs) between the output and the GND pin. The device will limit the output current to the programmed value when the voltage across Rs exceeds the internal threshold. Refer to the datasheet for more information.
  • Yes, the TPS40345DRCR can be used in a synchronous buck configuration. However, this requires additional external components, such as a synchronous rectifier FET and a bootstrap capacitor. Consult the datasheet and application notes for more information.
