Maxim provides a recommended PCB layout in the datasheet, but it's also important to follow general best practices for switching regulator layout, such as keeping the input and output capacitors close to the IC, and using a solid ground plane to reduce noise and EMI.
The datasheet provides a list of recommended inductors, but you can also use the following guidelines: choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value (typically between 1-10uH). You can also use Maxim's inductor selection tool to find a suitable inductor.
The datasheet specifies a maximum input voltage of 5.5V, but it's important to note that the IC can handle transient input voltages up to 6V for short durations (less than 100ms). However, it's recommended to keep the input voltage below 5.5V to ensure reliable operation.
The output voltage of the MAX8881EUT25-T can be adjusted by using a resistive divider network between the output pin and the feedback pin. The datasheet provides a formula to calculate the required resistor values for a specific output voltage.
The thermal shutdown temperature of the MAX8881EUT25-T is typically around 150°C, but this can vary depending on the specific device and operating conditions. It's recommended to consult the datasheet or contact Maxim support for more information.
