AOZ6605PI is a DC-DC switching regulator that can be used to regulate voltage for various types of applications. It adopts an external MOSFET to drive a PWM generator to provide high efficiency. This regulator is capable of producing output voltage up to 60V and also provides current-limiting, temperature protection and other features.

An advantage of AOZ6605PI is its wide input voltage range. It is able to provide a regulated output voltage within a voltage range from a minimum of 4.5 volts to a maximum of 60 volts. And it also has a wide range of output current capabilities that stretch from 50mA to 8A.

AOZ6605PI is a cost-effective solution for multiple applications. It is suitable for power supplies and digital power systems, providing support for general purpose or special digital systems with the necessary protection and efficiency requirements. It is also used in automatically charging batteries and digital products. Moreover, it can be used to provide constant output voltage and current while operating over a wide range of operating temperature.

The working principle of AOZ6605PI is fairly simple. It consists of a Gate Drive Control Circuit, a Current Sense Amplifier, a Boost Transistor and a RX Transistor. First, the Gate Drive Control Circuit will control the Boost Transistor to generate the switching frequency. Then, the Current Sense Amplifier compares the voltage generated by the sense resistor between the source of the Boost Transistor and ground to the output voltage of the regulator. The output voltage is determined by the ratio between the reference voltage and the sensed voltage. When the reference voltage rises, the output voltage also rises, and vice versa.

Once the output voltage reaches the desired value, the RX transistor will feedback to the Gate Drive Control Circuit, which then stops the pulse width modulation switching and the output voltage will maintain a constant value. In order to avoid damage caused by the over-current, the Current Sense Amplifier will detect the output current and will feed back to the Gate Drive Control Circuit to shut down the pulse width modulation. This will protect the regulator and the related devices.

AOZ6605PI is a reliable switching regulator that is suitable for a wide range of applications. It is capable of generating regulated output voltage with a wide range of input voltage and output current ratings. It is also protected by over-voltage, over-temperature, and over-current protection. In addition, with its low cost and easy integration, this regulator is a cost-effective solution for multiple applications.
