Alpha and Omega Semiconductor unveils high-performance SPS family

Alpha and Omega Semiconductor (AOS) announced a new series of Smart Power Stages (SPS) targeting multiphase VR regulators powering high-performance GPU and CPU in desktop Add-In Graphics Cards (AICs), gaming laptops, servers, data storage, artificial intelligence, and networking equipment.

The AOZ527xQI series uses AOS’s latest generation of a flexible smart driver IC and Gen Alpha MOSFET technology to provide benchmark performance in an industry-standard 5x6mm QFN package. The series comprises three DC current levels for multiphase voltage regulator optimization.

The AOZ527xQI uses a highly flexible and configurable driver IC to make this SPS compatible with many multiphase controllers in the market. It includes protection features such as Over-Current Protection (OCP), Over-Temperature Protection (OTP), High-Side FET Source Detect (HSD), and Pre-Over-Voltage Protection (Pre-OVP).

AOS’s SPS also features a unique dynamic control of OCP threshold settings and Zero-Cross Detect (ZCD) light load operation.

The performance is guaranteed, and all devices in this family feature high peak current capability, up to 150A for 10us and 100A for 10ms.
