The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help to reduce input voltage ripple and improve output voltage regulation.
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. Additionally, ensure that the input voltage is within the recommended range and the output current is within the specified limits.
The MAX6823SUK+T can deliver up to 2A of output current, but this depends on the input voltage, output voltage, and ambient temperature. Be sure to check the datasheet for the specific output current limits for your application.
The output voltage of the MAX6823SUK+T can be adjusted by using a resistive divider network between the output and the FB pin. The ratio of the resistors determines the output voltage. Refer to the datasheet for the specific equations and examples.
The MAX6823SUK+T is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Be sure to check the thermal design and ensure that the device is properly heat-sinked to prevent overheating.
