TPS3128E12DBVT Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS3128E12DBVT is 18V, but it's recommended to keep it below 15V for reliable operation.
  • To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor (at least 10uF), and add a 1uF capacitor between the EN pin and GND.
  • The minimum input voltage required for the TPS3128E12DBVT to operate is 2.5V, but it's recommended to keep it above 3V for reliable startup and operation.
  • The TPS3128E12DBVT is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliable operation.
  • The output voltage of the TPS3128E12DBVT is set by the resistive divider network connected to the FB pin. Use the formula: Vout = 1.2V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
