TPS54283PWPR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54283PWPR 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 suitable output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value. A 10uF to 22uF ceramic capacitor is recommended.
  • The EN (enable) pin is used to turn the regulator on or off. To turn the regulator on, connect the EN pin to VIN or a logic high signal. To turn the regulator off, connect the EN pin to GND or a logic low signal.
  • The output voltage of the TPS54283PWPR can be adjusted by using a resistor divider network between the VOUT pin and the GND pin. The output voltage is determined by the ratio of the resistors and the internal reference voltage.
  • The maximum output current that the TPS54283PWPR can deliver is 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
