TPS54327DRCR datasheet by Texas Instruments

TPS54327DRCR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54327DRCR?
  The maximum input voltage that can be applied to the TPS54327DRCR 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 suitable output capacitor with a low ESR (Equivalent Series Resistance) and a minimum capacitance of 10uF. Also, ensure that the input capacitor is properly sized and placed close to the device.
• What is the maximum output current that the TPS54327DRCR can deliver?
  The maximum output current that the TPS54327DRCR can deliver is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
• How do I adjust the output voltage of the TPS54327DRCR?
  The output voltage of the TPS54327DRCR can be adjusted by using a resistor divider network between the output and the FB (feedback) pin. The output voltage can be calculated using the formula: Vout = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
• What is the purpose of the EN (enable) pin?
  The EN (enable) pin is used to enable or disable the device. When the EN pin is pulled high, the device is enabled, and when it's pulled low, the device is disabled. This pin can be used to implement power sequencing or to shut down the device when not in use.
