The recommended input capacitor value is 10uF to 22uF, depending on the input voltage and output current requirements.
To ensure stability, make sure to follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and add a 10nF to 22nF capacitor between the FB pin and GND.
The maximum input voltage is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
The MAX825LEUK+T is rated for operation up to 125°C, but the output current may need to be derated at higher temperatures to prevent overheating.
The output voltage can be adjusted by connecting a resistor divider network between the output and the FB pin, and adjusting the resistors to achieve the desired output voltage.
