TPS79028DBVT datasheet by Texas Instruments

TPS79028DBVT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS79028DBVT?
  The maximum input voltage that can be applied to the TPS79028DBVT is 15V, but it's recommended to keep it below 13.2V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a minimum capacitance of 10uF and an ESR of less than 1 ohm. Additionally, the input capacitor should be at least 1uF with an ESR of less than 1 ohm.
• What is the minimum input voltage required for the TPS79028DBVT to operate?
  The minimum input voltage required for the TPS79028DBVT to operate is 2.7V, but it's recommended to keep it above 3V for reliable operation.
• Can I use the TPS79028DBVT in a high-temperature environment?
  The TPS79028DBVT is rated for operation up to 125°C, but it's essential to ensure that the device is properly heatsinked and the thermal design is adequate to prevent overheating.
• How do I calculate the output voltage of the TPS79028DBVT?
  The output voltage of the TPS79028DBVT can be calculated using the formula: Vout = 1.285 x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
