TPS77918DGK datasheet by Texas Instruments

TPS77918DGK Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS77918DGK?
  The maximum input voltage that can be applied to the TPS77918DGK is 18V, but it's recommended to keep it below 15V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, make sure to use a suitable output capacitor with a minimum capacitance of 10uF and a maximum ESR of 1 ohm. Also, ensure that the input voltage is within the recommended range and the device is operated within the specified temperature range.
• What is the minimum input voltage required for the TPS77918DGK to operate?
  The minimum input voltage required for the TPS77918DGK to operate is 2.7V, but it's recommended to keep it above 3V for reliable operation.
• Can I use the TPS77918DGK in a high-temperature environment?
  The TPS77918DGK is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
• How do I calculate the output voltage of the TPS77918DGK?
  The output voltage of the TPS77918DGK can be calculated using the formula: Vout = 1.8V * (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
