TPS75233QPWP datasheet by Texas Instruments

TPS75233QPWP Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS75233QPWP?
  The maximum input voltage is 15V, but it's recommended to keep it below 13.2V for optimal performance and to prevent overheating.
• How do I ensure the output voltage is stable and accurate?
  Use a high-quality output capacitor with a low ESR (Equivalent Series Resistance) and ensure the input voltage is stable and within the recommended range. Also, follow the recommended PCB layout guidelines to minimize noise and oscillations.
• What is the minimum input capacitance required for stability?
  A minimum of 1uF input capacitance is recommended, but 4.7uF or higher is recommended for optimal performance and stability.
• Can I use the TPS75233QPWP in a high-temperature environment?
  The TPS75233QPWP is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management to prevent overheating.
• How do I calculate the power dissipation and heat generation in the TPS75233QPWP?
  Use the formula: Pd = (Vin - Vout) x Iout. Then, calculate the junction temperature rise using the thermal resistance (RθJA) and the power dissipation. Ensure the junction temperature stays within the recommended range.
