TPS54418RTET Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54418RTET is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • To minimize EMI, it's recommended to keep the input and output capacitors close to the device, use a solid ground plane, and keep the high-current paths short and wide. Additionally, use a shielded inductor and orient it to minimize radiation.
  • The recommended output capacitor value is 10uF to 22uF, and it's recommended to use a low-ESR ceramic or polymer capacitor to minimize output voltage ripple and ensure stability.
  • The output voltage of the TPS54418RTET can be adjusted by using a resistor divider network between the VOUT pin and the GND pin. The recommended resistor values are R1 = 10kΩ and R2 = 2.49kΩ for a 1.8V output, but these values can be adjusted to achieve the desired output voltage.
  • The thermal derating curve for the TPS54418RTET is not explicitly provided in the datasheet, but it can be estimated based on the device's thermal resistance (θJA) and the maximum junction temperature (TJ). As a general guideline, the device's output current should be derated by 1.5% per degree Celsius above 25°C.
