A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input capacitors close to the IC and use short, wide traces for the power lines. Avoid routing sensitive analog signals near the switching node.
The inductor value depends on the input voltage, output voltage, and switching frequency. A good starting point is to use the inductor value recommended in the datasheet. You can also use the inductor selection guide provided by Maxim Integrated Products or consult with their application engineers.
The MAX17501EATB+ is rated for operation from -40°C to +125°C. However, the device's performance and reliability may degrade at extreme temperatures. It's essential to ensure proper thermal management and consider derating the device's performance at high temperatures.
Yes, the MAX17501EATB+ is AEC-Q100 qualified and suitable for automotive and high-reliability applications. However, it's essential to follow the recommended design and layout guidelines, and to consult with Maxim Integrated Products' application engineers to ensure the device meets the specific requirements of your application.
Start by checking the PCB layout, component values, and soldering quality. Verify that the input voltage, output voltage, and switching frequency are within the recommended specifications. Use an oscilloscope to monitor the output voltage and switching node waveforms. Consult the datasheet and application notes for troubleshooting guidelines, and contact Maxim Integrated Products' technical support if needed.
