TPS5420MDREP Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS5420MDREP is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10uF ceramic capacitor between the VIN and GND pins. Additionally, use a low-ESR output capacitor and keep the output voltage ripple below 1%.
  • The minimum input capacitance required is 10uF, but it's recommended to use a 22uF or larger ceramic capacitor to ensure stability and optimal performance.
  • The TPS5420MDREP 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 reliability and prevent thermal shutdown.
  • The output voltage of the TPS5420MDREP can be adjusted by using a resistor divider network between the VOUT and GND pins. The recommended resistor values can be calculated using the formula provided in the datasheet.
