TPS2121RUXT Frequently Asked Questions (FAQs)

  • The maximum current rating of the TPS2121RUXT is 2A per channel, with a total current limit of 4A for both channels combined.
  • To ensure proper thermal management, it is recommended to provide a thermal pad on the PCB, use a heat sink if necessary, and ensure good airflow around the device. The junction-to-ambient thermal resistance (RθJA) is 30°C/W.
  • The EN (enable) pin is used to enable or disable the device. When EN is high, the device is enabled, and when EN is low, the device is disabled and in a low-power state.
  • The output voltage of the TPS2121RUXT can be configured using an external resistor divider network connected to the FB (feedback) pin. The output voltage is determined by the ratio of the resistors in the divider network.
  • The minimum input voltage required for the TPS2121RUXT is 2.7V, but it is recommended to use an input voltage of at least 3.0V to ensure proper operation.
