The recommended layout and placement for the MAX17595ATE+ involves keeping the device away from high-current carrying traces, using a solid ground plane, and placing the input capacitors close to the device. A 4-layer PCB with a dedicated power plane is also recommended. Refer to the Maxim Integrated Products application note AN5121 for more details.
The input capacitors should be selected based on the input voltage, output voltage, and output current requirements. A minimum capacitance of 10uF is recommended, with a voltage rating of at least 1.5 times the maximum input voltage. X5R or X7R ceramic capacitors are suitable for most applications. Refer to the datasheet for more information.
The EN (enable) pin is used to turn the device on or off. When the EN pin is high, the device is enabled and operates normally. When the EN pin is low, the device is disabled and enters a low-power shutdown mode, reducing the quiescent current to less than 1uA.
The output voltage of the MAX17595ATE+ can be adjusted by connecting a resistive divider network between the output and the FB (feedback) pin. The resistive divider network sets the output voltage based on the internal reference voltage of 0.8V. Refer to the datasheet for more information on how to calculate the resistor values.
The maximum output current capability of the MAX17595ATE+ is 500mA. However, the output current should be derated based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
