AOZ5006QI-01 Working Principle：

The working principle of the AOZ5006QI-01 is relatively simple. It utilizes a synchronous buck controller to transfer energy from a input voltage to an adjustable output voltage. The output voltage can be set from 2.5V to 5.5V and the input voltage has a range from 2.5V to 28V.

The device utilizes a high-frequency oscillator that runs at high frequency to provide a pulse-width modulation (PWM) signal to the synchronous buck controller. This allows for precise control of the output voltage. When the output voltage is close to the set point, the PWM signals turns off and the device enters quiescent, or idle state.

The output voltage is then determined by the feedback voltage that is delivered to the synchronous buck controller. This feedback voltage is compared to the reference voltage and then applied to a current correction network. This network then adjusts the duty cycle of the PWM signal and thereby the output voltage.

The AOZ5006QI-01 also includes current limit protection, which prevents the device from overloading. This is achieved by monitoring the current level through a sense resistor and stopping the PWM signal when the current exceeds the preselected maximum.

In addition to its efficiency and high performance, the AOZ5006QI-01 has also been designed for low power consumption. It is designed for operation up to 80% efficiency, enabling the device to save energy and reduce system cost.
