Delta Electronics recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure good heat dissipation. A minimum of 2 oz copper thickness is recommended.
To ensure reliable operation in high-temperature environments, it's essential to provide adequate heat sinking, ensure good airflow, and follow the recommended derating curves for the device. Additionally, consider using a thermal interface material (TIM) to improve heat transfer between the device and the heat sink.
The maximum allowable voltage deviation on the input pins is ±10% of the nominal input voltage. Exceeding this limit may affect the device's performance, reliability, or even cause damage.
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 voltage is within the specified range. Also, verify that the device is not overheating and that the input voltage is within the recommended range.
Delta Electronics recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF for the input capacitor. This helps to filter out high-frequency noise and ensure stable operation.
