BD9874CP-V5E2 Frequently Asked Questions (FAQ)

  • ROHM recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended, and the thermal pad should be connected to a ground plane or a dedicated heat sink.

  • To ensure stable operation with a high-impedance input source, add a 1-10nF capacitor in parallel with the input resistor to reduce noise and oscillation. Additionally, consider adding a 10-100Ω resistor in series with the input to reduce the impedance.

  • Although the datasheet doesn't specify a maximum voltage for the EN pin, ROHM recommends keeping it within the VCC range (typically 3.3V or 5V) to ensure proper operation and prevent damage to the device.

  • While the BD9874CP-V5E2 is rated for operation up to 125°C, ROHM recommends derating the output current and power dissipation at high temperatures to ensure reliable operation. Consult ROHM's application notes for specific guidance on high-temperature operation.

  • To troubleshoot oscillations or instability issues, check the PCB layout for proper decoupling, ensure the input and output capacitors are of sufficient value and quality, and verify that the device is operated within the recommended voltage and current ranges. Also, consider adding a small resistor (e.g., 10Ω) in series with the output to dampen oscillations.
