Operation Principle:The MAX8867EUK29+T utilizes a traditional voltage-regulator architecture with an added internal power switch that allows the device to achieve high efficiency and minimal power loss. The device includes an n-channel metal-oxide-semiconductor field-effect transistor (MOSFET) that is connected between the input supply and the regulator output. When no input voltage is applied, the MOSFET is off. When a voltage is applied, it turns on and enables the regulator circuit. The regulator then converts the input voltage to a lower, regulated output voltage according to the desired voltage set by an external feedback voltage. Output limitation and over-temperature protection are provided. The device also features an internal power switch, which is designed to minimize power dissipation in the device.
