AOZ2260QI-10 is an integrated, synchronous, low-side MOSFET, step-down DC-DC switching regulator controller from Diodes Inc. The device combines high efficiency and fast transient response performance into a flexible, feature-rich and small package.

The device is commonly used as a voltage regulator in various applications such as PCs, notebooks, tablets and embedded designs. It operates from a 4.5V to 20V input voltage range and provides up to 4A output current. By implementing the PWM current mode architecture, the AOZ2260QI-10 supports high switching frequency and fast transient response without external compensation.

In order to minimize system time-to-market and reduce design complexity, the device provides several advanced features such as integrated input overvoltage protection, output soft-start/soft-stop and dynamic voltage positioning during startup. Furthermore, the device has a high speed enable/disable response.

The working principle of the AOZ2260QI-10 is to modulate the on-time of its integrated high-side and low-side MOSFETs in order to regulate the output voltage. The device receives a voltage reference at its input pin and compares the output voltage value with the reference value. Based on the difference between them, the on-time of the switching becomes longer or shorter in order to control the output voltage.

In summary, the AOZ2260QI-10 from Diodes Inc is an integrated synchronous switching regulator controller specifically designed for voltage regulation applications. It features fast transient response, high efficiency, 4.5V to 20V input voltage range, 4A output current and a wide range of advanced features.
