The AOZ1044PI-01 is a DC-DC switching regulator compatible with USB Type-C™ and Power Delivery applications. With the addition of advanced protection features, this device enables the design of secure reliable systems for power adapter, charger, and embedded system applications.

The AOZ1044PI-01 offers high performance across a wide range of DC-DC buck converters used in expanding range of application such as Adaptive Fast Charger, USB PD (Power Delivery) Type-C devices, server and telecom systems. The device offers superior efficiency and robust protection features such as OVP, OTP, and OCP.

This device is suitable for mobile phones, laptops, and tablets. As it is USB PD Type-C compatible, it supports fast-charging, and enables quick charge of any device. It also offers low quiescent current, high efficiency, and high power level.

The device comprises PWM control circuitry and an integrated MOSFETs. This allows the device to produce the exact output voltage during normal operation and to protect the downstream components even if the output voltage is out of regulation.

The AOZ1044PI-01 operates in the boundary conduction mode, offering low EMI (electro-magnetic interference). This makes the device suitable for automotive and consumer applications. The MOSFETs also feature integrated soft-start capability, which reduces switching losses.

The device also features a power good output and programmable over-voltage protection of up to 54V. This protects the downstream components and allows for high voltage operation up to 54V for use in high-voltage applications such as 12V to 48V systems.

The AOZ1044PI-01 also features an adjustable output current limit. This feature helps to protect the device from over- current. During fault conditions, the device will automatically limit the output current to reduce the load on the system, while also helping to protect the device.

The device has a maximum operating frequency of 1MHz and is user-programmable. This allows the device to be used in a wide range of applications. The device also features a thermal shutdown protection feature which prevents damage to the device in the event of over temperature.

A wide range of package types are available, including an 8-pin intag package, dimple, industry-standard TSOP, and QFN. This enables designers to choose the most suitable package for their application.

In summary, the AOZ1044PI-01 is a DC-DC switching regulator that is compatible with USB Type-C and Power Delivery with added protection features. Its unique features and versatile package options make it suitable for a wide range of applications.
