Murata recommends a 4-layer PCB with a solid ground plane on the bottom layer, and a split power plane on the top layer. The input and output capacitors should be placed close to the device, and the feedback network should be routed away from the input and output lines.
To ensure stability, make sure the output capacitor is a low-ESR type, and the feedback network is properly compensated. Also, ensure the input voltage is within the recommended range, and the output load is within the specified range.
The maximum ambient temperature for the 84103C is 85°C, with a maximum junction temperature of 125°C. However, it's recommended to derate the output power at high temperatures to ensure reliable operation.
Yes, the 84103C is designed to meet the requirements of high-reliability and aerospace applications. However, it's recommended to consult with Murata's application engineers to ensure the device meets the specific requirements of your application.
To troubleshoot issues with the 84103C, start by checking the input voltage, output voltage, and output current. Use an oscilloscope to check for oscillations or noise on the output. Also, verify the PCB layout and component values meet the recommended specifications.
