TPS54429ERSAR datasheet by Texas Instruments

TPS54429ERSAR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54429ERSAR?
  The maximum input voltage that can be applied to the TPS54429ERSAR is 18V. Exceeding this voltage may damage the device.
• How do I ensure the stability of the output voltage in the TPS54429ERSAR?
  To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF with an ESR of 1ohm or less, and to place the output capacitor close to the output pin of the device.
• What is the maximum output current that the TPS54429ERSAR can deliver?
  The maximum output current that the TPS54429ERSAR can deliver is 4A. Exceeding this current may cause the device to overheat or shut down.
• How do I adjust the output voltage of the TPS54429ERSAR?
  The output voltage of the TPS54429ERSAR can be adjusted by using a resistor divider network between the output pin and the feedback pin. The output voltage can be calculated using the formula: Vout = 0.8V x (R1 + R2) / R2.
• What is the purpose of the enable pin on the TPS54429ERSAR?
  The enable pin on the TPS54429ERSAR is used to turn the device on or off. When the enable pin is pulled high, the device is enabled and the output voltage is regulated. When the enable pin is pulled low, the device is disabled and the output voltage is disconnected.
