Alpha and Omega Semiconductor Unveils 16 Phase Controller That Supports Further AI Server and Graphic Card Innovation<\/b><\/p>\n

Specifically designed to NVIDIA\u2019s latest OpenVreg16 Phase specifications, the AOZ73016QI delivers a highly efficient, flexible power solution when paired with AOS\u2019 power stages<\/i><\/p>\n

SUNNYVALE, Calif.–(BUSINESS WIRE<\/a>)–Alpha and Omega Semiconductor Limited<\/a> (AOS) (Nasdaq: AOSL), a designer, developer, and global supplier of a broad range of discrete power devices, wide bandgap power devices, power management ICs, and modules, today unveiled its AOZ73016QI<\/a>, a 16-Phase, 2-rail controller specifically designed to the latest OpenVReg16 (OVR16) specifications from NVIDIA. The AOZ73016QI controller design is based on the company\u2019s high performance, proprietary AOS Advanced Transient Modulator (A2<\/sup>TM) control scheme. In addition to supporting all the basic requirements of the OVR16 specification, the new AOS controller offers value-added features such as RDS(on) and DCR sensing for current monitoring and current balance. These features enable AOS\u2019 controller to support both DrMOS and Smart Power Stages (SPS) to deliver a complete AI server and graphic card power solution along with increased design flexibility.<\/p>\n

\nThe AOZ73016QI control scheme offers excellent current balance at all load conditions as well as during fast load transients, which is a critical requirement for power-hungry AI and graphics SoCs that demand over several thousands of amperes of peak current. It also capably handles phase doubling or tripling without the addition of a phase doubler so a single controller can support up to a 48-phase design. When paired with AOS\u2019 high performance DrMOS and SPS power stages utilizing AOS\u2019 highly efficient and robust trench MOSFET, the AOS solution offers industry leading efficiency and thermals saving several hundred watts of power during high transient current events that can last for a few 100s of microseconds and up to 1 millisecond when the SoC draws peak power. In a head-to-head comparison against a leading competitor product, each of the AOS\u2019 5 x 5 DrMOS power stages were shown to dissipate 14W lower power loss during these peak current events.<\/p>\n

\nThe AOZ73016QI supports an accurate RDS(on) sensing scheme, which uses power stage low side MOSFET RDS(on) sensing, thus enabling the use of low DCR inductors to help boost system efficiency. The device\u2019s automatic phase management (APM) and auto discontinuous mode (DCM) power saving features extend its usability to graphics cards and gaming laptops.<\/p>\n

\nThe AOZ73016QI offers full programmability via the PMBUS interface and is also AVS bus compliant. The device features digitally programmable voltage and current regulation loops minimizing the external components required to implement a solution. It supports electronic control system (ECS) programmability with ability to update configuration in the field, and to pre-program up to six configuration settings with a pin-strap selection.<\/p>\n

\n\u201cAOS has a long history of developing leading-edge personal computing, server and datacenter solutions. The launch of our successful AOZ73016QI 16-phase controller for OVR16-based designs is the culmination of several years of R&D investment in multiphase controllers. Developed in close collaboration with our customers’ system architects, the AOZ73016QI is a robust, reliable power solution for more advanced AI servers. Plus, the design flexibility afforded by the AOZ73016QI helps lower TCO for next generation AI servers,” said Ralph Monteiro, Sr. VP, Power IC and Discrete Product lines at AOS.<\/p>\n
