Investor Overview

Investor Overview

Alpha and Omega Semiconductor Limited, or AOS, is a designer, developer and global supplier of a broad range of power semiconductor products.

AOS's portfolio of products target high-volume applications, including portable computers, flat panel TVs, LED lighting, smart phones, battery packs, consumer and industrial motor controls, and power supplies for TVs, computers, servers and telecommunications equipment.

AOS has developed extensive intellectual property and technical knowledge that encompasses the latest advancements in the power semiconductor industry, which enables us to introduce innovative products to address the increasingly complex power requirements of advanced electronics.  AOS differentiates itself by integrating its Discrete and IC semiconductor process technology, product design, and advanced packaging know-how to develop high performance power management solutions, and our goal is to become a total power semiconductor solution provider.

AOS has two major categories of products: power discretes and power ICs.   AOS’s power discrete products consist primarily of low, medium and high voltage power MOSFETs.  The primary function of power MOSFETs is to deliver power by switching, transferring or converting electricity.  AOS has made advances in its mid-voltage portfolio by offering Best In Class performance for telecommunications and industrial power supply applications. In addition, its high-voltage portfolio was expanded to include proprietary insulated-gate bipolar transistor ("IGBT") technology, for which AOS developed robust and easy-to-use solutions designed for industrial motor control, welding, induction heating, renewable energy inverters and white goods applications.

For power ICs, AOS employs a multi-chip approach that allows us to update a product by interchanging only the MOSFETs without changing the power management IC, thereby reducing the time required for new product introduction.  These compact and high efficiency devices are ideal for the consumer, computing and communication market segments.
