TPS54331DRG4 datasheet by Texas Instruments

TPS54331DRG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54331DRG4?
  The maximum input voltage that can be applied to the TPS54331DRG4 is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the stability of the output voltage?
  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 output capacitor is placed close to the output pin of the IC.
• What is the maximum output current that the TPS54331DRG4 can deliver?
  The maximum output current that the TPS54331DRG4 can deliver is 3A, but it's recommended to keep it below 2.5A for reliable operation.
• How do I adjust the output voltage of the TPS54331DRG4?
  The output voltage of the TPS54331DRG4 can be adjusted by using a resistive divider network between the output pin and the ground pin. The output voltage can be calculated using the formula: Vout = 0.8V * (R1 + R2) / R2.
• What is the purpose of the EN pin on the TPS54331DRG4?
  The EN (enable) pin on the TPS54331DRG4 is used to enable or disable the output voltage. When the EN pin is high, the output voltage is enabled, and when it's low, the output voltage is disabled.
