BD9E104FJ-E2 Frequently Asked Questions (FAQs)

  • A recommended PCB layout for optimal thermal performance would be to have a large copper area on the bottom layer connected to the thermal pad, and to use thermal vias to dissipate heat. A minimum of 2oz copper thickness is recommended.
  • To ensure the stability of the output voltage, it is recommended to use a capacitor with a low ESR (Equivalent Series Resistance) and a high ripple current rating. A 10uF to 22uF capacitor with an ESR of less than 1 ohm is recommended.
  • Although the datasheet specifies a maximum input voltage of 18V, it is recommended to limit the input voltage to 15V to ensure reliable operation and to prevent damage to the device.
  • To protect the device from overcurrent, it is recommended to add an external current limiting resistor or a fuse in series with the input voltage. The current limit should be set to 1.5A to 2A to prevent damage to the device.
  • A 1uF to 10uF ceramic capacitor with an X5R or X7R dielectric is recommended for the input capacitor. This will help to filter out noise and ensure stable operation.
