ROHM provides a recommended PCB layout in the application note AN12242, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
The input capacitor selection depends on the input voltage, output voltage, and output current. ROHM recommends using a low-ESR ceramic capacitor with a value between 1uF to 10uF, and a voltage rating of at least 1.5 times the input voltage.
The BM6249FS-E2 is rated for operation up to 105°C ambient temperature, but ROHM recommends derating the output current and voltage to ensure reliable operation above 85°C.
ROHM provides a troubleshooting guide in the application note AN12243, which covers common issues such as output voltage regulation, oscillation, and overcurrent protection. It's recommended to check the input voltage, output voltage, and output current, as well as the PCB layout and component selection.
Yes, the BM6249FS-E2 is compatible with lead-free soldering processes, and ROHM recommends following the JEITA ED-4701 standard for lead-free soldering.
