TPS54527DDAR datasheet by Texas Instruments

TPS54527DDAR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54527DDAR?
  The maximum input voltage that can be applied to the TPS54527DDAR 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, it's essential to use a suitable output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value. A 10uF to 22uF ceramic capacitor is recommended.
• What is the minimum input capacitance required for the TPS54527DDAR?
  The minimum input capacitance required for the TPS54527DDAR is 10uF, but it's recommended to use a 22uF to 47uF capacitor for better performance.
• Can I use the TPS54527DDAR in a high-temperature environment?
  The TPS54527DDAR is rated for operation up to 125°C, but it's essential to consider the thermal design and ensure that the junction temperature (TJ) does not exceed 150°C.
• How do I calculate the output voltage of the TPS54527DDAR?
  The output voltage of the TPS54527DDAR can be calculated using the formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
