Murata recommends a symmetrical PCB layout with a solid ground plane, and keeping the input and output traces as short as possible. A 4-layer PCB with a dedicated power plane and a dedicated ground plane is also recommended.
To ensure reliability in high-temperature environments, Murata recommends following the derating guidelines in the datasheet, using a heat sink or thermal pad, and ensuring good airflow around the converter.
The maximum capacitance for the output filter capacitor is not explicitly stated in the datasheet, but Murata recommends using a capacitor with a maximum value of 10uF to 22uF to ensure stability and prevent oscillation.
Yes, the 48681SC can be used in a redundant or parallel configuration, but Murata recommends following specific guidelines and design considerations to ensure proper operation and to prevent damage to the converters.
While the datasheet specifies a minimum input voltage of 3.5V, Murata recommends an input voltage range of 4.5V to 5.5V for optimal performance and to ensure the converter's internal voltage regulators operate within their specified range.
