TPS72115DBVTG4 datasheet by Texas Instruments

TPS72115DBVTG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS72115DBVTG4?
  The maximum input voltage that can be applied to the TPS72115DBVTG4 is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
• How do I ensure the stability of the output voltage in the TPS72115DBVTG4?
  To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value. A 10uF to 22uF ceramic capacitor is recommended.
• What is the minimum input voltage required for the TPS72115DBVTG4 to operate?
  The minimum input voltage required for the TPS72115DBVTG4 to operate is 2.7V, but it's recommended to keep it above 3V for optimal performance and reliability.
• Can I use the TPS72115DBVTG4 in a high-temperature environment?
  The TPS72115DBVTG4 is rated for operation up to 125°C, but it's essential to ensure that the device is properly heatsinked and that the junction temperature is kept below 125°C to prevent thermal shutdown.
• How do I calculate the output voltage of the TPS72115DBVTG4?
  The output voltage of the TPS72115DBVTG4 can be calculated using the formula: Vout = 1.221V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
