TPS79428DGNT Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS79428DGNT is 15V, but it's recommended to keep it below 13.2V for optimal performance and to prevent damage to the device.
  • To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a minimum capacitance of 2.2uF and an ESR of less than 1 ohm. Additionally, the output capacitor should be placed as close to the output pin as possible.
  • The minimum input capacitance required for the TPS79428DGNT is 1uF, but it's recommended to use a higher value (e.g., 4.7uF) to ensure stable operation and to filter out noise and ripple.
  • The TPS79428DGNT is rated for operation up to 125°C, but it's essential to ensure that the device is properly derated for high-temperature operation. The output current should be reduced accordingly to prevent overheating and damage to the device.
  • The power dissipation of the TPS79428DGNT can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current. It's essential to ensure that the power dissipation is within the recommended limits to prevent overheating and damage to the device.
