Murata recommends a 4-layer PCB with a solid ground plane on the bottom layer, and a microstrip layout for the input and output lines. A detailed layout guide is available in the Murata application note AN43SW1.
To ensure reliability, Murata recommends following the derating guidelines for the output power and input voltage based on the ambient temperature. Additionally, ensure good thermal design, including a heat sink and adequate airflow, to keep the junction temperature below 125°C.
Although not specified in the datasheet, Murata recommends keeping the input voltage ripple below 100mVp-p to ensure stable operation and prevent oscillations.
Yes, the PWR1311AC can be used in a redundant power supply configuration. However, it's essential to ensure that the input voltage and output voltage are properly synchronized to prevent damage to the device or the system.
The typical start-up time for the PWR1311AC is around 10ms to 15ms, depending on the input voltage and output load conditions. This information is not specified in the datasheet but can be obtained from Murata's application engineers or technical support.
