The MAX6920AWP+T requires careful layout and routing to minimize noise and ensure optimal performance. Maxim recommends following a star-grounding scheme, keeping the power and ground traces separate, and using a solid ground plane. Additionally, the input and output traces should be routed away from each other and from the power and ground traces.
The output voltage setting resistors (R1 and R2) should be chosen based on the desired output voltage and the input voltage range. Maxim provides a resistor selection guide in the datasheet, and online calculators can also be used to determine the correct resistor values.
The MAX6920AWP+T can handle input voltages up to 28V, but the absolute maximum rating is 30V. However, it's recommended to operate the device within the recommended input voltage range of 4.5V to 28V to ensure optimal performance and reliability.
The MAX6920AWP+T is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. Maxim recommends derating the device's output current and voltage at high temperatures, and ensuring proper thermal management to prevent overheating.
To troubleshoot issues with the MAX6920AWP+T, start by verifying the input voltage and output load conditions. Check the layout and routing for noise and signal integrity issues, and ensure that the output capacitors are properly sized and placed. If the issue persists, consult the datasheet and application notes for troubleshooting guidelines, or contact Maxim's technical support team for assistance.
