AOZ73004QI - NVIDIA OpenVReg Compliant Controller Multi-Phase Controller

Datasheet Summary

Description

The AOZ73004QI is a high performance multi-phase buck controller designed in compliance with NVIDIA OpenVReg specifications.

It provides one output rail and supports PWMVID interface.

AOS offers a novel AOS Advanced Transient Modulator (A2TM).

Features

  • are external reference input and PWMVID dynamic output voltage control, in which the output voltage is regulated and tracks external input reference voltage. The PWMVID duty cycle determines the variable output voltage at REFIN, Vmin is the zero percent duty cycle voltage value. Vmax is the one hundred percent duty cycle voltage value. AOZ73004QI can be paired and supports multi-sourced industry standard DrMOS and Smart Power Stage (SPS). AOZ73004QI is offered in compact 4mm x 4mm 32-pin QFN pac.

AOZ73004QI NVIDIA OpenVReg Compliant Controller Multi-Phase (≤ 4 Phase) Controller with PWMVID Interface General Description The AOZ73004QI is a high performance multi-phase buck controller designed in compliance with NVIDIA OpenVReg specifications. It provides one output rail and supports PWMVID interface. AOS offers a novel AOS Advanced Transient Modulator (A2TM). It combines an advanced variable frequency hysteretic peak current mode control with proprietary phase current sensing scheme for fast transient response and low system cost. The control loop enhances light-load efficiency by seamlessly entering DCM mode of operation. Autonomous Phase Management also assures the optimized efficiency and power loss during light load with single phase DCM mode.
