BD9329AEFJ-E2 Frequently Asked Questions (FAQ)

  • A good PCB layout for the BD9329AEFJ-E2 should include a solid ground plane, wide power traces, and a thermal relief pattern under the IC to facilitate heat dissipation. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.

  • To ensure stable operation with a high-ESR output capacitor, it's recommended to add a 1-10nF ceramic capacitor in parallel with the output capacitor to reduce the ESR. Additionally, the output capacitor should be placed close to the IC to minimize the loop inductance.

  • The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the IC. It's recommended to use a voltage divider or a level shifter to ensure the EN pin voltage does not exceed 6V.

  • The output voltage ripple can be calculated using the following formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.

  • A 10-22uF ceramic or electrolytic capacitor with a low ESR is recommended for the input capacitor. The capacitor should be placed close to the IC to minimize the loop inductance.
