TPS56121DQPR Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the TPS56121DQPR is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.

  • To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the input capacitance is at least 10uF and the input voltage is within the recommended range.

  • The maximum output current that the TPS56121DQPR can deliver is 1.5A, but it's recommended to keep it below 1.2A for optimal performance and reliability.

  • The output voltage of the TPS56121DQPR can be adjusted by using a resistor divider network between the output and the ADJ pin. The output voltage can be calculated using the formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.

  • The EN (enable) pin on the TPS56121DQPR is used to enable or disable the regulator. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled. This pin can be used to implement power sequencing or to turn off the regulator when not in use.
