TPS22941DCKR Frequently Asked Questions (FAQs)

  • The maximum current rating of the TPS22941DCKR 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 all outputs are turned off.
  • The output voltage of the TPS22941DCKR can be configured using external resistors (R1 and R2) connected to the FB (feedback) pin. The output voltage is calculated using the formula: Vout = 0.8V x (1 + R2/R1).
  • The minimum input voltage required for the TPS22941DCKR is 2.5V, but it is recommended to use a minimum input voltage of 3V for proper operation.
