BD6981FVM-GTR Frequently Asked Questions (FAQs)
-
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 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.
-
The BD6981FVM-GTR 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 specific guidance on high-temperature operation.
-
To troubleshoot oscillations or instability issues, check the PCB layout for parasitic inductance and capacitance, ensure proper decoupling, and verify that the output capacitor is suitable for the application. Also, check the input voltage and current, and ensure that the IC is operated within its recommended specifications.
