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.
ROHM recommends using an output capacitor with an ESR of 10mΩ or less. Additionally, a 1μF or larger ceramic capacitor in parallel with the output capacitor can help stabilize the output voltage.
The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the device.
The BD6520F-E2 is rated for operation up to 105°C. However, derating the output current and ensuring proper thermal design are necessary to ensure reliable operation at high temperatures.
The output voltage accuracy can be calculated by considering the internal reference voltage accuracy, resistor tolerance, and output voltage divider ratio. ROHM provides a calculation formula in the application note.
