ROHM 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 essential to use a common mode choke and a pi-filter to reduce EMI.
To ensure stability, it's crucial to use a sufficient output capacitor (at least 10uF) with a low ESR, and to place it as close to the output pin as possible. Additionally, the input capacitor should be at least 1uF with a low ESR.
The maximum ambient temperature for the RFUH20TJ6SGC9 is 105°C, but it's recommended to operate it at a temperature below 85°C for optimal performance and reliability.
Yes, the RFUH20TJ6SGC9 is designed to withstand high vibrations, but it's essential to ensure that the PCB is properly secured and that the components are properly soldered to prevent damage.
To troubleshoot issues, start by checking the input voltage, output voltage, and current consumption. Verify that the PCB layout and component placement meet the recommended guidelines. If the issue persists, consult the datasheet and application notes or contact ROHM's technical support.
