The recommended layout and routing for the MAX1920EUT+T involves keeping the input and output traces separate, using a solid ground plane, and minimizing the length of the input traces. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
The MAX1920EUT+T requires a single 2.7V to 5.5V power supply. It's recommended to use a low-dropout linear regulator or a switching regulator with a low noise output to power the device. The power sequencing requirements involve powering up the device in the following order: VCC, EN, and then VIN.
The MAX1920EUT+T has a thermal pad that must be connected to a thermal plane on the PCB to ensure proper heat dissipation. The device can operate up to 85°C, but it's recommended to keep the junction temperature below 70°C to ensure optimal performance and reliability.
Common issues with the MAX1920EUT+T can be troubleshooted by checking the input voltage, output voltage, and feedback loop. Ensure that the input voltage is within the recommended range, the output voltage is within the specified tolerance, and the feedback loop is properly connected. Oscillations can be caused by improper layout, noise on the input or output, or incorrect component values.
The MAX1920EUT+T is designed to meet EMI and EMC regulatory standards, but it's still important to follow proper PCB layout and design practices to minimize emissions and susceptibility. Ensure that the device is properly shielded, use a common-mode choke on the input, and follow proper cable shielding and routing practices.
