ROHM provides a recommended PCB layout in the application note AN1794, which includes guidelines for component placement, thermal vias, and copper pouring to ensure optimal thermal performance and noise reduction.
The input capacitor selection depends on the input voltage, output voltage, and output current. ROHM recommends using a low-ESR capacitor with a capacitance value between 10uF to 22uF, and a voltage rating of at least 1.5 times the input voltage. Refer to the application note AN1794 for more details.
The maximum ambient temperature for the BD37544FS-E2 is 85°C, but it can be derated to 70°C for long-term reliability. Refer to the datasheet for thermal derating curves and guidelines.
Yes, the BD37544FS-E2 is designed to withstand high vibrations. ROHM recommends following the guidelines in the application note AN1794 for PCB design and component selection to ensure reliability in high-vibration environments.
ROHM provides a troubleshooting guide in the application note AN1794, which covers common issues such as output voltage deviation, oscillation, and overheating. Additionally, engineers can contact ROHM's technical support for further assistance.
