TPS79433DCQ datasheet by Texas Instruments

TPS79433DCQ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS79433DCQ?
  The maximum input voltage that can be applied to the TPS79433DCQ 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 recommended to use a minimum output capacitance of 2.2uF 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 TPS79433DCQ to operate?
  The minimum input voltage required for the TPS79433DCQ to operate is 2.7V, but it's recommended to keep it above 3V for reliable operation.
• Can I use the TPS79433DCQ in a high-temperature environment?
  The TPS79433DCQ is rated for operation up to 125°C, but the output current and voltage regulation may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curve in the datasheet.
• How do I calculate the power dissipation of the TPS79433DCQ?
  The power dissipation of the TPS79433DCQ 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.
