AOZ3112DI is a dual channel NanoPower buck converter with a built-in 1A gate driver that is suitable for use in portable applications. The wide 6V-32V input voltage range and extremely low quiescent current make the AOZ3112DI an ideal solution for today’s energy challenging applications. It improves the efficiency, extends the battery life and reduces the overall power application size.

The AOZ3112DI is designed for DC-DC switch mode power supply applications including small handsets, tablet PCs, mobile media players and other power sensitive products. The device operates at a fixed frequency of 2 MHz and features an enable pin, which is used to enable or disable the converter. The AOZ3112DI also features built-in soft-start and soft idle modes, which reduce the inrush currents to the load by gradually increasing the output voltage to the desired voltage level. Additionally, the device includes cycle-by-cycle current limit, Thermal Shutdown (TSD), and Over Temperature Protection (OTP) to ensure the device operates in a safe operating condition.

AOZ3112DI is a high-efficiency, low-power buck regulator that uses Pulse Width Modulation (PWM) control. The device consists of an optimized IC that enables a small package size and high power density. It is compatible with a wide range of available integrated inductors. The PWM control enables voltage regulators to achieve high efficiency, good reliability, and excellent noise performance.

The AOZ3112DI includes an adjustable voltage range of 0.9V to 2.5V that can be set using an external voltage divider. Additionally, the device also features an output voltage tracking pin, which allows multiple AOZ3112DI devices to be controlled in parallel for higher output current applications. The output ripple is minimized through the inclusion of an internal compensation network.

The AOZ3112DI provides a wide range of protection features that include input under voltage protection, thermal shutdown, over current protection, and short circuit protection. In addition, the device also includes a programmable soft start feature that helps reduce inrush current during startup. The device also prevents catastrophic failure during power surges, such as when USB connections are used.

Overall, the AOZ3112DI is a cost-effective, energy efficient, and high-performance device that is suitable for a wide range of DC-DC switch mode power supply applications. It features an adjustable voltage range, a programmable soft-start feature, an enable pin, an output voltage tracking pin, an internal compensator, and protection features. The device is easy to design using with its integrated inductors. The device also allows multiple AOZ3112DI devices to be controlled in parallel for higher output current applications.
