AOZ2264QI-15 is a DC/DC switching converter which combines voltage regulator with the boost (or step-up) power management applications. The device can operate from an input voltage range of 2.5V to 12V and output a regulated voltage ranging from 3.3V to 24V. It is intended for providing power to a wide range of applications such as automation and industrial/IoT equipment, audio and video systems, robots, and other applications.

AOZ2264QI-15 DC/DC switching converter provides efficient, low noise and high peak current operation over the full rated input range by providing an internal synchronous switch which allows the energy stored in an inductive element to supply the output current. In addition, the low voltage output (VOUT) option can operate the device up to 0.8V output voltage providing efficient energy saving during sleep mode or low battery operation. Low standby current of 2.2uA minimizes the power consumption when the converter is not in active mode.

The AOZ2264QI-15 switching regulator can provide several power management functions including power-on reset, open-circuit protection, under-voltage protective shutdown, and temperature shutdown. The device also incorporates a soft start function to reduce the inrush current and provide output voltage ramp-up control. The external compensation network allows for optimization of the device\'s performance over the entire input voltage range and load range.

AOZ2264QI-15 includes a couple of internal selectable frequency modes (400kHz/800kHz) for switching converters. The 400kHz setting minimizes switching losses and increases the efficiency of the device, while the 800kHz mode increases the output power and enables the device to remain within the temperature limits.

AOZ2264QI-15 is a single-phase synchronous step-up switcher which provides the high efficiency and low heat generated while using small external components and low cost components. The device is capable of providing a high efficiency of up to 97% over the full range of input voltage and provides an output ripple voltage of less than 10mVpp. The wide input voltage range of 2.5V-12V makes it suitable for a wide range of industrial applications.

AOZ2264QI-15 integrates protection features such as under-voltage lockout, over-temperature protection, and short-circuit protection. Allowing for the safe operation of the device, the over-temperature protection keeps the device from reaching temperatures above a predetermined limit, and the short-circuit protection prevents the output voltage from reaching a damaging level. The under-voltage lockout prevents the device from operating under unsafe input voltages.

AOZ2264QI-15 integrates all the necessary functions for a compact, single-chip solution. The device features an on-board current-mode PWM controller and low-ripple synchronous rectifier (SR) with a very low switching loss over the wide input voltage and load range, making it ideal for applications requiring high efficiency, low noise, and small size. Designers can customize the output voltage and ripple characteristics through the external compensation network.

AOZ2264QI-15 is a cost-effective, low-noise, and high-efficiency DC/DC switching converter that is suitable for a wide range of applications. The device provides efficient power conversion, superior current and voltage regulation, and wide input voltage ranges. The integration of multiple protection features also ensures safe operation while the adjustable frequency settings allow optimization of the performance and efficiency of the device over the entire input voltage and load range.
