EVPASAC1A Details

Panasonic recommends a 4-layer PCB with a solid ground plane and a separate power plane for the AC-DC converter. The layout should also minimize the loop area of the high-frequency circuits to reduce EMI.
To ensure reliability in high-temperature environments, it is recommended to follow the derating guidelines provided in the datasheet, and to ensure good thermal management by providing adequate heat sinking and airflow around the device.
The maximum allowable voltage drop across the input capacitors is 10% of the input voltage. Exceeding this limit may affect the performance and reliability of the EVPASAC1A.
While it is possible to use other types of input capacitors, it is not recommended as they may not provide the same level of performance and reliability as the recommended X7R or X5R capacitors.
To troubleshoot issues with the EVPASAC1A, it is recommended to follow a systematic approach, starting with checking the input voltage, output voltage, and current, and then verifying the PCB layout and component values. Panasonic also provides application notes and technical support to help with troubleshooting.
