TPS5100IPW datasheet by Texas Instruments

TPS5100IPW Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS5100IPW?
  The maximum input voltage that can be applied to the TPS5100IPW is 18V, but it's recommended to keep it below 15V for reliable operation.
• How do I ensure the TPS5100IPW is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor (at least 10uF), and add a 1uF capacitor between the VIN and EN pins.
• What is the minimum input voltage required for the TPS5100IPW to operate?
  The minimum input voltage required for the TPS5100IPW to operate is 6.5V, but it's recommended to keep it above 7V for reliable startup.
• Can I use the TPS5100IPW in a high-temperature environment?
  The TPS5100IPW is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliable operation.
• How do I calculate the output voltage of the TPS5100IPW?
  The output voltage of the TPS5100IPW is set by the resistive divider network connected to the FB pin. Use the formula: VOUT = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
