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 recommends using a low-ESR output capacitor (less than 10 ohms) to ensure stable operation. If a high-ESR capacitor is used, a series resistor can be added to dampen the oscillation.
The maximum allowed voltage on the EN pin is 6V, which is higher than the recommended operating voltage of 5V. However, it's recommended to keep the EN pin voltage within the recommended operating range to ensure reliable operation.
The BD16805FV-ME2 is rated for operation up to 105°C, but ROHM recommends derating the output current and voltage to ensure reliable operation at high temperatures. Consult the datasheet and ROHM's application notes for more information.
ROHM recommends checking the PCB layout, output capacitor selection, and input voltage stability. Ensure that the input voltage is within the recommended range, and the output capacitor is properly selected and placed. Consult ROHM's application notes and technical support for further assistance.
