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, and the thermal pad should be connected to a ground plane to reduce thermal resistance.
To ensure stable operation with a high-ESR output capacitor, ROHM recommends adding a 1nF to 10nF ceramic capacitor in parallel with the output capacitor to reduce the overall ESR. Additionally, the output capacitor should be placed close to the IC to minimize parasitic inductance.
The maximum allowed voltage on the EN pin is 6V, which is higher than the recommended operating voltage of 5V. However, it's essential to ensure that the EN pin voltage does not exceed 6V to prevent damage to the IC.
While the BD6512F-E2 is rated for operation up to 105°C, ROHM recommends derating the output current and voltage to ensure reliable operation in high-temperature environments. Consult the datasheet and ROHM's application notes for specific guidance on thermal derating.
To troubleshoot oscillations or instability issues, check the PCB layout for parasitic inductance and capacitance, ensure proper decoupling of the input and output capacitors, and verify that the output capacitor is within the recommended range. Additionally, check for noise on the EN pin and ensure that it is properly filtered.
