TPS71518DCKR Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the TPS71518DCKR is 6.5V, as specified in the datasheet. However, it's recommended to operate the device within the recommended input voltage range of 2.7V to 5.5V for optimal performance and reliability.

  • To ensure stability and prevent oscillations in the TPS71518DCKR, it's essential to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 1uF), and ensure that the input capacitor is properly sized and placed close to the device. Additionally, the device should be operated within the recommended input voltage range and output current range.

  • The minimum output capacitance required for the TPS71518DCKR is 1uF, as specified in the datasheet. However, it's recommended to use a higher capacitance value (e.g., 2.2uF or 4.7uF) to ensure stability and optimal performance, especially in applications with high output current or high-frequency noise.

  • The TPS71518DCKR is rated for operation up to 125°C, but it's essential to consider the device's thermal characteristics and ensure that the junction temperature (TJ) does not exceed 150°C. Proper thermal design, including heat sinking and airflow, is crucial to ensure reliable operation in high-temperature environments.

  • The power dissipation of the TPS71518DCKR can be calculated using the formula: Pd = (VIN - VOUT) x IOUT, where Pd is the power dissipation, VIN is the input voltage, VOUT is the output voltage, and IOUT is the output current. Additionally, the device's thermal resistance (RθJA) and junction temperature (TJ) should be considered to ensure reliable operation.
