AOZ71026QI

Multiphase Controllers

The AOZ71026QI is a high performance digital and analog hybrid multiphase buck controller designed in compliance with Intel IMVP8, 9 and 9.1/9.2 platform specifications. It provides two output rails (up to 4 + 2) and supports 3 separate SVID domains. Up to 4 phases for core voltage domain (IA) and 2 phases for graphics voltage domain (GT) as well as the PSYS domain’s reporting functions, incorporated into a single SVID interface. AOS offers a novel AOS Advanced Transient Modular (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.
