ROHM provides a recommended PCB layout in their application note AN0914, 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 desired ripple voltage. 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 datasheet and application notes for more information.
The maximum output current of the SLR343WBN2PT is 3A, but it's recommended to derate the output current based on the ambient temperature and PCB layout to ensure reliable operation. Consult the datasheet and thermal derating curves for more information.
To ensure stability, follow the recommended PCB layout, use a suitable input capacitor, and add a 1uF to 10uF output capacitor. Additionally, ensure that the output voltage is within the specified range, and the input voltage is above the minimum required value. Consult the datasheet and application notes for more information.
ROHM recommends using an output capacitor with an ESR of less than 1 ohm to ensure stability and minimize output voltage ripple. Consult the datasheet and application notes for more information.
