TPS51020DBT Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS51020DBT 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 capacitor to ensure stability and low input voltage ripple.
  • The TPS51020DBT is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage according to the thermal derating curve in the datasheet.
  • The output voltage of the TPS51020DBT is set by the resistive divider network consisting of R1 and R2. The output voltage can be calculated using the formula: VOUT = 0.8V x (1 + R2/R1).
