TPS77515D datasheet by Texas Instruments

TPS77515D Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS77515D?
  The maximum input voltage that can be applied to the TPS77515D is 15V, but it's recommended to keep it below 13.2V to ensure reliable operation.
• How do I ensure the TPS77515D is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the device and use a low-ESR capacitor for the output.
• What is the minimum input voltage required for the TPS77515D to operate?
  The minimum input voltage required for the TPS77515D to operate is 2.7V, but it's recommended to keep it above 3V for reliable operation.
• Can I use the TPS77515D in a high-temperature environment?
  The TPS77515D is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
• How do I calculate the output voltage of the TPS77515D?
  The output voltage of the TPS77515D is set by the resistive divider network connected to the FB pin. Use the formula Vout = 1.25V x (R1 + R2) / R2 to calculate the output voltage.
