To minimize EMI, it is recommended to place the MAX253ESA+T close to the power source, use a solid ground plane, and keep the input and output traces as short as possible. Additionally, use a common-mode choke or ferrite bead on the input lines to filter out high-frequency noise.
To ensure proper decoupling, place a 0.1uF ceramic capacitor between the VIN pin and GND, and a 10uF electrolytic capacitor between the VIN pin and GND. This will help filter out high-frequency noise and ensure stable operation.
The MAX253ESA+T can handle input voltages up to 40V, but it is recommended to operate within the specified input voltage range of 4.5V to 36V for optimal performance and reliability.
The output voltage of the MAX253ESA+T can be adjusted by using a resistive divider network between the FB pin and the output voltage. The ratio of the resistors determines the output voltage, and the datasheet provides a formula to calculate the required resistor values.
The MAX253ESA+T can deliver up to 3A of output current, but it is recommended to operate within the specified output current range of 0A to 2.5A for optimal performance and reliability.
