The recommended PCB layout for optimal thermal performance involves placing thermal vias under the IC, using a solid ground plane, and keeping the thermal path as short as possible. A 4-layer PCB with a dedicated thermal layer is also recommended.
To ensure reliable operation in high-temperature environments, it's essential to follow the recommended operating temperature range, use a heat sink or thermal pad, and ensure good airflow around the device. Additionally, consider using a thermal interface material (TIM) to improve heat transfer.
Operating the NJM8532RB1-TE2 at the maximum rated voltage (36V) may reduce its lifespan and increase the risk of overheating. It's recommended to operate the device at a voltage below the maximum rating to ensure reliable operation and extend its lifespan.
To troubleshoot issues with the device's output voltage regulation, check the input voltage, output load, and feedback resistors. Ensure that the feedback resistors are correctly connected and that the output capacitor is suitable for the application. Also, verify that the device is not overheating.
To minimize EMI and EMC issues, use a shielded enclosure, keep the device away from sensitive circuits, and use a common-mode choke or ferrite bead on the input lines. Additionally, ensure that the PCB layout is designed to minimize radiation and coupling.
