ROHM recommends a PCB layout with a solid ground plane, short and wide traces for power and ground, and a decoupling capacitor (e.g., 100nF) close to the IC. A 4-layer PCB with a dedicated power plane is also recommended.
Ensure good thermal design, including a heat sink if necessary, and avoid exposing the device to extreme temperatures during storage or operation. The device is rated for -40°C to 125°C operation, but derating may be necessary for high-power applications.
A 10uF to 22uF ceramic capacitor (X5R or X7R dielectric) is recommended for the input capacitor. This value provides a good balance between noise filtering and stability.
Yes, the BV1LC105FJ-CE2 is AEC-Q100 qualified and suitable for automotive and high-reliability applications. However, ensure that your design meets the specific requirements of the target application, including environmental and testing standards.
Check the PCB layout, component selection, and soldering quality. Verify that the input voltage, output load, and ambient temperature are within the specified ranges. Use oscilloscopes and thermal imaging cameras to identify potential issues. Consult ROHM's application notes and technical support resources for further guidance.
