ROHM provides a recommended PCB layout in their application note AN1191, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
The input capacitor selection depends on the input voltage, output current, and ripple current requirements. ROHM recommends using a low-ESR capacitor with a value between 1uF to 10uF, and a voltage rating of at least 1.5 times the input voltage. Consult the application note AN1191 for more details.
According to ROHM's application note AN1191, the maximum output current derating for high ambient temperatures is approximately 1.5A at 85°C and 1A at 105°C. However, this may vary depending on the specific application and thermal design.
Yes, the BD18341FV-ME2 is AEC-Q100 qualified and suitable for high-reliability and automotive applications. However, it's essential to consult ROHM's reliability report and follow their guidelines for automotive applications.
To ensure EMC, follow ROHM's guidelines for PCB layout, component selection, and shielding. Additionally, consider using a common-mode choke and capacitors to filter out electromagnetic interference (EMI). Consult ROHM's application note AN1191 for more details.
