The AP3105NAKTR-G1 is a highly-efficient, 2A-rated fixed frequency, Buck switching regulator. It is part of a class of PMIC – AC DC converters and offline switchers that are used in a variety of applications including battery charging, adapter charging, DC-DC regulation, and other power regulation tasks. This particular device offers a wide range of features, including a wide 4.5 V to 28 V input voltage range, programmable current limit, thermal shutdown protection, and a selectable current limit between 1.2 A and 2 A.

The AP3105NAKTR-G1 is a synchronous buck converter which works by rapidly switching an inductor on and off with a controllable frequency, usually between 200 to 600kHz. The output is regulated by modulating the duty cycle of the pulses. When the inductor is switched on, energy is stored in its magnetic field as current begins to flow. When it is switched off, that energy is released through the output to charge a capacitor and maintain a constant output voltage.

The AP3105NAKTR-G1 has numerous advantages over older, non-switching regulator designs. Switchers are smaller, lighter, and more efficient, which makes them more suitable for portable applications. They don\'t suffer from high drop-off at light load, as linear regulators do, and they don\'t generate large amounts of wasted heat.

The AP3105NAKTR-G1 is an ideal solution for battery charging, providing highly accurate current limiting and regulation with few external components and small PCB area requirement. It can be used in adapters and portables to provide reliable output voltage regulation, as well as in DC-DC conversion with high efficiency and high current delivery capability.

The device also offers several protective features. It includes a thermal shutdown protection system which will automatically shut down the output when the die temperature exceeds a preprogrammed limit, essentially protecting against overloads and shorts. It also offers selectable current limit values, programmable using two external resistors, and a low dropout voltage for improved efficiency and low power dissipation.

In summary, the AP3105NAKTR-G1 is a highly efficient, 2A-rated, fixed frequency synchronous buck switching regulator. It is part of a class of PMICs – AC DC converters and offline switchers, suitable for a wide range of applications. It features a wide range of features, including a wide 4.5 V to 28 V input voltage range, programmable current limit, thermal shutdown protection, and a selectable current limit between 1.2 A and 2 A. The device is suitable for use in battery charging, adapter charging, DC-DC regulation, and other power regulation tasks.
