Working Principles

The MAX8902AATA/V+T is a voltage regulator IC that takes an input voltage in the range of 2.7V to 5.5V and provides a regulated output voltage in the range of 1.2V to 3.6V. It achieves this by utilizing a switching regulator architecture, which allows for high efficiency power conversion.

The enable pin (EN) controls the operation of the regulator. When the EN pin is high, the regulator is enabled and actively regulates the output voltage. Conversely, when the EN pin is low, the regulator enters a low-power standby mode, reducing quiescent current.

The feedback pin (FB) is used to set the desired output voltage. By connecting an external resistor divider network between the output voltage pin (VOUT) and the FB pin, the output voltage can be precisely adjusted.

Detailed Application Field Plans

The MAX8902AATA/V+T is commonly used in various battery-powered portable devices, such as smartphones, tablets, and wearable devices. Its small package size and low quiescent current make it ideal for applications where space and power efficiency are crucial.

Additionally, it finds applications in IoT devices, medical devices, and other portable electronics that require efficient power management solutions.
