BD2206G-TR - ROHM Semiconductor

BD2206G-TR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  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.
• How do I ensure stable operation with a high-ESR output capacitor?
  ROHM recommends using an output capacitor with an ESR of 10mΩ or less to ensure stable operation. Additionally, a 1μF or larger ceramic capacitor in parallel with the output capacitor can help to reduce oscillation.
• What is the maximum allowed voltage on the EN pin?
  The maximum allowed voltage on the EN pin is 6V, exceeding which may cause damage to the device. It is recommended to use a voltage divider or a clamp circuit to limit the voltage to 6V or less.
• Can I use the BD2206G-TR in a high-temperature environment?
  While the BD2206G-TR is rated for operation up to 125°C, ROHM recommends derating the output current and voltage to ensure reliable operation in high-temperature environments. Consult the datasheet for derating curves and guidelines.
• How do I troubleshoot oscillation or instability issues with the BD2206G-TR?
  ROHM recommends checking the PCB layout, output capacitor selection, and input voltage ripple to identify the root cause of oscillation or instability. Additionally, reducing the output capacitor value or adding a small resistor in series with the output capacitor can help to stabilize the output.
