AOZ3017PI is an advanced double-output smart Power Management Integrated Circuit (PMIC) specifically designed for use in high power portable devices, personal computers and servers. It is a DC-DC switching regulator that integrates two outputs: a 4.5V to 18V adjustable output and a low temperature-coefficient 0.8V fixed output. With on-chip high voltage FETs, MOSFETs and low voltage transistors, the AOZ3017PI ensures high efficiency, wide adjustable output voltage range and good dynamic response to load transients. Moreover, the AOZ3017PI is designed for applications with minimal external components.

AOZ3017PI employs a peak current control mode to regulate the output voltage from 4.5V to 18V. It primarily uses an internal MOSFET to regulate output voltage in this mode, but if the duty cycle exceeds the safety threshold, the MOSFET will be switched off, and an external FET will be used to control the peak current. The AOZ3017PI also features overvoltage and undervoltage protection, over-current protection, current limit protection and short-circuit protection.

The AOZ3017PI also comes with a 0.8V fixed output. This output is designed to be used with low voltage circuits like flash memories and microcontrollers. Its low temperature coefficient ensures that the output voltage remains stable even when exposed to large temperature variations. Additionally, the AOZ3017PI is designed to be adjustable from 4.5V to 18V, so it can be used for different battery-powered applications.

In order to allow for precise output control, the AOZ3017PI features an advanced voltage feed-forward control loop that adjusts the output current according to the input voltage. This control loop also features a low temperature coefficient to ensure the output current remains stable even when the input voltage varies. Moreover, the AOZ3017PI also implements an internal current-sense amplifier that can detect the load current in real time and quickly respond to load transients.

The AOZ3017PI is available in an 8-pin International Rectifier package that is suitable for low profile and medium power applications. Furthermore, it provides different programmable options like output voltage tracking, soft-start and delay power-on to ensure a safe and stable system.

The AOZ3017PI is an ideal PMIC for notebook computers, tablets, smartphones and other portable applications. It is designed to operate in automotive and harsh environment and provides low voltage and high efficiency DC-DC switching regulator for power supply applications.
