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 4-layer PCB with a thermal via is also recommended.
ROHM suggests using a low-ESR output capacitor (less than 10 ohms) to ensure stable operation. If a high-ESR capacitor is used, additional compensation may be required to prevent oscillation.
The maximum allowed voltage on the EN pin is 6V, exceeding which may cause damage to the device. It's recommended to use a voltage divider or a clamp circuit to limit the voltage to 6V or less.
While the BD37068FV-ME2 is rated for operation up to 105°C, ROHM recommends derating the output current and voltage to ensure reliable operation in high-temperature environments (above 85°C).
ROHM suggests checking the PCB layout, output capacitor selection, and input voltage ripple. Ensure that the device is operated within the recommended operating conditions, and consider adding additional compensation or filtering if necessary.
