The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help reduce input ripple and improve transient response.
To ensure stability, make sure to follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and add a small ceramic capacitor (e.g., 10nF) between the FB pin and GND. Also, avoid using a capacitor with high ESL (Equivalent Series Inductance) on the output.
The MAX811TEUS can handle input voltages up to 28V, but it's recommended to keep the input voltage below 24V for optimal performance and reliability.
The MAX811TEUS is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the output current and ensure good thermal design to prevent overheating.
The output voltage can be adjusted by using a resistive divider network between the FB pin and GND. The ratio of the resistors determines the output voltage, which can be calculated using the formula provided in the datasheet.
