TPS23881B1RTQR Frequently Asked Questions (FAQs)

  • A good PCB layout is crucial for the TPS23881B1RTQR. TI recommends a 4-layer PCB with a solid ground plane, and the use of vias to connect the GND pins to the ground plane. Keep the high-current paths short and wide, and use a common node for the input and output capacitors.
  • Choose input capacitors with low ESR (Equivalent Series Resistance) and high ripple current rating. For output capacitors, select ones with low ESR, high capacitance, and a voltage rating that meets or exceeds the output voltage. TI recommends using X5R or X7R ceramic capacitors.
  • The TPS23881B1RTQR is rated for operation up to 85°C ambient temperature. However, for reliable operation, it's recommended to keep the ambient temperature below 70°C to ensure the device stays within its thermal specifications.
  • The TPS23881B1RTQR has built-in OVP and UVP features. For OVP, connect a resistor divider network to the OVP pin to set the desired overvoltage threshold. For UVP, connect a resistor divider network to the UVP pin to set the desired undervoltage threshold.
  • The recommended input voltage range for the TPS23881B1RTQR is 2.7V to 5.5V. Operating the device outside this range may affect its performance and reliability.
