TPS74401RGWR datasheet by Texas Instruments

TPS74401RGWR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS74401RGWR can handle?
  The TPS74401RGWR can handle input voltages up to 12V, but it's recommended to operate within the specified input voltage range of 2.7V to 10V for optimal performance.
• How do I ensure the stability of the output voltage?
  To ensure stability, it's essential to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 10uF), and maintain a minimum output load of 1mA.
• What is the maximum output current that the TPS74401RGWR can provide?
  The TPS74401RGWR can provide up to 1A of output current, but it's recommended to derate the output current based on the input voltage and ambient temperature to ensure reliable operation.
• How do I adjust the output voltage of the TPS74401RGWR?
  The output voltage of the TPS74401RGWR can be adjusted by connecting a resistor divider network between the output and the ADJ pin. The output voltage can be calculated using the formula: Vout = 1.24V x (1 + R1/R2).
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to turn the regulator on or off. To enable the regulator, connect the EN pin to a logic high (VIN or higher). To disable the regulator, connect the EN pin to a logic low (GND).
