TPS54329EDDAR datasheet by Texas Instruments

TPS54329EDDAR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54329EDDAR?
  The maximum input voltage that can be applied to the TPS54329EDDAR 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 the recommended output capacitor values and types, and keep the output voltage within the specified range (0.9V to 15V).
• What is the minimum input capacitance required for stable operation?
  The minimum input capacitance required for stable operation is 10uF, but it's recommended to use a 22uF or larger capacitor to ensure stability across the entire input voltage range.
• Can I use the TPS54329EDDAR in a high-temperature environment?
  Yes, the TPS54329EDDAR can operate in high-temperature environments, but the maximum junction temperature should not exceed 150°C. Make sure to follow the thermal design guidelines to ensure reliable operation.
• How do I calculate the output current capability of the TPS54329EDDAR?
  The output current capability of the TPS54329EDDAR can be calculated using the formula: Iout = (Vin - Vout) / Rds(on) x (1 - duty cycle), where Vin is the input voltage, Vout is the output voltage, Rds(on) is the on-state resistance, and duty cycle is the ratio of the on-time to the total switching period.
