TPS54426RSAT Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54426RSAT is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • To minimize EMI and noise, it's recommended to follow the layout guidelines provided in the datasheet, including keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces.
  • The recommended output capacitor value is 10uF to 22uF, and it's recommended to use a low-ESR ceramic capacitor, such as an X5R or X7R type, to ensure stable operation and minimize output voltage ripple.
  • The output voltage of the TPS54426RSAT can be adjusted by using a resistive divider network between the output and the FB pin, and by selecting the appropriate values for R1 and R2 resistors according to the desired output voltage.
  • The maximum output current that the TPS54426RSAT can deliver is 4A, but it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
