TPS79028DBVR datasheet by Texas Instruments

TPS79028DBVR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS79028DBVR?
  The maximum input voltage that can be applied to the TPS79028DBVR is 15V, but it's recommended to keep it below 13.2V to ensure reliable operation.
• How do I ensure the stability of the output voltage in the TPS79028DBVR?
  To ensure the stability of the output voltage, it's recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the input capacitance should be at least 1uF.
• What is the minimum input voltage required for the TPS79028DBVR to operate?
  The minimum input voltage required for the TPS79028DBVR to operate is 2.7V, but it's recommended to keep it above 3V for reliable startup.
• Can I use the TPS79028DBVR in a high-temperature environment?
  The TPS79028DBVR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage to ensure reliable operation at high temperatures.
• How do I calculate the power dissipation of the TPS79028DBVR?
  The power dissipation of the TPS79028DBVR can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current.
