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 to ensure stable operation. Additionally, a 1μF or larger ceramic capacitor in parallel with the output capacitor can help improve stability.
The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the device.
The BD6967FVM-TR is rated for operation up to 125°C. However, derating is required for temperatures above 85°C. Consult the datasheet for derating curves and thermal management guidelines.
The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
