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 main 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 BD12734F-GE2 is rated for operation up to 105°C. However, derating the output current and ensuring proper thermal management are necessary to ensure reliable operation in high-temperature environments.
Power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout x Efficiency. ROHM provides a power dissipation calculator on their website to simplify this calculation.
