BA33DD0T Frequently Asked Questions (FAQs)

  • A thermal pad on the bottom of the package should be connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
  • Use an output capacitor with an ESR of 10 ohms or less to ensure stable operation. Additionally, add a 1uF ceramic capacitor in parallel with the output capacitor to improve stability.
  • The maximum input voltage that can be applied to the VIN pin is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
  • The BA33DD0T is rated for operation up to 105°C, but the maximum junction temperature should not exceed 125°C. Ensure proper heat sinking and thermal design to maintain a safe operating temperature.
  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout x ESL) / (Cout x fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
