A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output tracks as short as possible and use a common mode choke to reduce EMI.
Use a high-quality output capacitor with low ESR, ensure the input voltage is within the recommended range, and add a 10nF capacitor between the VCC pin and GND to filter out noise.
The maximum input voltage is 18V, but it's recommended to keep it below 15V to ensure reliable operation and prevent overheating.
The device is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management to prevent overheating.
Check the input voltage, output capacitor, and PCB layout. Ensure the output capacitor is of high quality and the PCB tracks are short and well-decoupled. Also, verify that the input voltage is within the recommended range.
