TPS5430DDARG4 datasheet by Texas Instruments

TPS5430DDARG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS5430DDARG4?
  The maximum input voltage that can be applied to the TPS5430DDARG4 is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the TPS5430DDARG4 is stable and doesn't oscillate?
  To ensure stability, make sure to use the recommended output capacitor value and type, and keep the input capacitor value within the recommended range. Also, ensure the PCB layout is well-designed and follows good practices for switching regulators.
• What is the minimum input voltage required for the TPS5430DDARG4 to operate?
  The minimum input voltage required for the TPS5430DDARG4 to operate is 6.5V, but it's recommended to keep it above 7V for reliable startup and operation.
• Can I use the TPS5430DDARG4 in a high-temperature environment?
  The TPS5430DDARG4 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
• How do I calculate the output voltage of the TPS5430DDARG4?
  The output voltage of the TPS5430DDARG4 can be calculated using the formula: Vout = (R1 / R2) * 0.8V, where R1 and R2 are the resistors used in the feedback network.
