TPS40071PWPRG4 Frequently Asked Questions (FAQs)

  • TI recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to minimize thermal impedance. A minimum of 2 oz copper thickness is recommended for the top layer.
  • To ensure stable output voltage, use a high-quality input capacitor (e.g., X5R or X7R ceramic) with a minimum capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, consider adding a feedforward capacitor (e.g., 1nF) between the VIN and VOUT pins to improve transient response.
  • The maximum output current capability of the TPS40071PWPRG4 is 7A, but it's recommended to derate the output current to 5A or less to ensure reliable operation and minimize thermal stress.
  • Use an external voltage supervisor (e.g., TLV7031) to monitor the input voltage and generate a reset signal to the TPS40071PWPRG4 in case of overvoltage or undervoltage conditions. Additionally, consider adding a TVS diode (e.g., SMF05C) to protect the device from voltage transients.
  • TI recommends using a low-ESR ceramic capacitor (e.g., X5R or X7R) with a minimum capacitance of 10uF and a maximum ESR of 1 ohm. A larger input capacitor can help improve input voltage ripple rejection and reduce output voltage noise.
