PMIC - Voltage Regulators - DC DC Switching Regulators are a type of voltage regulator that provides a constant voltage output through the conversion of an input voltage. The AOZ1267QI-02 is a DC-DC switching buck regulator that is capable of providing a wide output voltage range, up to 5V and adjustable current up to 6A, while allowing a high switching frequency up to 1MHz. This makes it suitable for a variety of applications including digital, industrial, automotive, and power supplies.

The AOZ1267QI-02 features thermal shut-down protection, overcurrent protection, and soft-start. It also has a low quiescent current of 17mA at no load, making it highly efficient and saving power in applications. The device supports a wide input voltage range from 4.0 V to 20 V, and delivers a regulated 5V up to 6A. Its high switching frequency of up to 1MHz allows for efficient conversion of the input voltage to the output voltage, resulting in minimal energy loss.

The AOZ1267QI-02 uses a synchronous buck topology and is operated in a pulse-width modulation (PWM) mode. The device has two power switches, an internal voltage reference and an error amplifier. The external components include input and output caps, a compensation network, bootstrap diode, and a Schottky or synchronous rectifier. The internal voltage reference is used as feedback to the error amplifier, which compares the output voltage to the internal reference. The error amplifier adjusts the duty cycle of a PWM switch to regulate the output voltage to the desired level.

The AOZ1267QI-02 is a highly efficient, low-power, DC-DC switching regulator, capable of delivering up to 6A at 5V with a wide input voltage range. Its chipset allows it to use a high switching frequency for fast and efficient conversion, minimizing loss of energy. Its low quiescent current of 17mA helps to save power in applications, and its thermal shut-down protection, overcurrent protection, and soft-start features add to its safety and reliability. Due to its features and performance, the AOZ1267QI-02 is suitable for a wide range of applications including digital, industrial, automotive, and power supplies.
