BD63441AFU-E2 Frequently Asked Questions (FAQs)

  • A good PCB layout for optimal thermal performance would be to have a solid ground plane on the bottom layer, and to use thermal vias to connect the thermal pad of the IC to the ground plane. This helps to dissipate heat efficiently.
  • To ensure stable operation with a high-ESR output capacitor, it's recommended to add a small ceramic capacitor (e.g. 1uF) in parallel with the output capacitor to improve the overall ESR and reduce the risk of oscillation.
  • The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the IC.
  • While it's technically possible to use a lower value for the bootstrap capacitor, it's not recommended as it may affect the stability of the converter. The recommended value is 100nF, and using a lower value may cause the converter to oscillate or malfunction.
  • The power dissipation of the IC can be calculated using the formula: Pd = (Vin x Iin) + (Vout x Iout) + (Switching losses). The datasheet provides more information on how to calculate the switching losses.
