Panasonic recommends a 4-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible. Additionally, it's recommended to use a common mode choke or a ferrite bead to filter out high-frequency noise.
The DRC2143E0L is rated for operation between -40°C to 125°C. Ensure proper heat dissipation by providing adequate airflow, using a heat sink if necessary, and avoiding high-power density designs. Also, consider derating the device's power handling at higher temperatures.
Panasonic recommends using X7R or X5R ceramic capacitors with a value of 10uF to 22uF for input and output filtering. The capacitor's voltage rating should be at least 1.5 times the maximum input voltage.
Use a voltage regulator or a TVS diode to protect the device from overvoltage conditions. For overcurrent protection, consider using a fuse or a current-limiting resistor in series with the input. Additionally, ensure the PCB design can handle the maximum current rating of the device.
The typical start-up time for the DRC2143E0L is around 10ms to 20ms, depending on the input voltage and output load. However, this time can vary depending on the specific application and design.
