The recommended operating voltage range for the MAX3816ACUE+ is 2.7V to 5.5V.
To ensure the MAX3816ACUE+ is in a low-power state, make sure the SHDN pin is pulled high (logic level 1) and the EN pin is pulled low (logic level 0).
The EN (enable) pin is used to enable or disable the output of the MAX3816ACUE+. When EN is high, the output is enabled, and when EN is low, the output is disabled.
The output voltage of the MAX3816ACUE+ can be adjusted by using an external resistor divider network connected to the FB (feedback) pin.
The maximum output current of the MAX3816ACUE+ is 1A.
