ROHM recommends a thermal pad design with a minimum size of 2.5mm x 2.5mm, and a thermal via array with a minimum of 9 vias, 0.3mm in diameter, and 1.5mm pitch to ensure optimal thermal performance.
The input capacitor should be selected based on the input voltage ripple, output voltage, and output current requirements. A general guideline is to use a capacitor with a capacitance value of 10uF to 22uF, and a voltage rating of 25V to 50V, depending on the specific application.
The maximum allowed voltage deviation on the input pin is ±10% of the nominal input voltage. Exceeding this deviation may affect the device's performance and reliability.
The BM2SC122FP2-LBZE2 is rated for operation up to 105°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and ensure proper thermal management to ensure reliable operation.
To ensure EMC, it's recommended to follow proper PCB layout guidelines, use a shielded enclosure, and add filtering components such as ferrite beads and capacitors to reduce electromagnetic interference (EMI).
