The AOZ1094AIL, a member of the PMIC - Voltage Regulators - DC DC Switching Regulators category, is a high-efficiency, wide-input DC/DC buck regulator with both synchronous rectification and FF Selimut technologies. It is designed to provide an output current up to 7A and can support wide input voltage ranging from 3.4V to 30V. With such capability, the AOZ1094AIL is ideal for powering applications such as consumer mobile, industrial, automotive, etc.

In terms of working principle, the AOZ1094AIL works by first using an internal error amplifier to compare a feedback voltage with a 0.8V reference voltage and then responds by adjusting the duty cycle of the internal driver, which turns on and off an external N-Channel MOSFET. This switching frequency is controlled by an internal oscillator at fixed frequency. An internal soft start feature also prevents inrush current during startup.

The AOZ1094AIL further offers a wide range of options for flexible settings, including adjustable switching frequency from 200kHz to 3MHz and adjustable loop compensation, enabling it to satisfy a wide range of applications. Other features include 100% duty cycle for low dropout output, adjustable UVLO and thermal shutdown for better performance. For improved noise immunity, the dual N-Channel MOSFETs provides improved noise immunity for both input and output.

The AOZ1094AIL also contains certain safety and reliability features to ensure that the system is operating within its ratings and not exceeding the rated power dissipation. For instance, the AOZ1094AIL features an adjustable overvoltage protection (OVP), undervoltage lockout (UVLO), load current limit and thermal shutdown.

In addition, the AOZ1094AIL is simple to use and requires only a minimal amount of external components to work properly. This reduces component count and board size, making it ideal for small, space-constrained applications. As such, the AOZ1094AIL is a highly efficient and reliable DC/DC buck regulator that is ideal for a wide range of power supply applications.
