Alpha and Omega Semiconductor to Feature Groundbreaking Controllers for AI and Robust Packaging Advancements at APEC 2025
March 5, 2025 | Alpha and Omega SemiconductorEstimated reading time: 1 minute
Alpha and Omega Semiconductor Limited (AOS), a designer, developer, and global supplier of a broad range of discrete power devices, wide band gap power devices, power management ICs, and modules will showcase its complete line of advanced power management solutions at the Applied Power Electronics Conference (APEC). These new products offer advanced features enabling designers to meet power management challenges in several key application areas.
Booth highlights:
Datacenters, AI Server, and High-Performance Graphics Cards: AOS is showcasing two new controllers specifically designed for high-performance GPUs and SoCs used in graphics cards and AI servers. The AOZ73016QI is a 16-phase, 2-rail controller specifically designed to the latest OpenVReg16 (OVR16) specifications. The AOZ73016QI controller design is based on the company’s high-performance, proprietary AOS Advanced Transient Modulator (A2TM) 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 balance. These features enable AOS’ controller to support DrMOS and Smart Power Stages (SPS) to deliver a complete AI server and graphic card power solution and increase design flexibility. The 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 the ability to update configuration in the field and to pre-program up to six configuration settings with a pin-strap selection.
As the world’s first OVR4-22 multiphase PWM controller, the AOZ73004CQI has received full OpenVReg OVR4-22 compliance. Its advanced design helps safely throttle GPU power for maximized performance. It leverages AOS’ breakthrough control scheme that meets stringent power delivery requirements with minimum external components and offers world-class system power efficiency.
When paired with AOS’ industry-leading DrMOS and Smart Power Stages, the AOZ73016QI and AOZ73004CQI form a complete solution for GPU or AI SoC power in datacenters, graphics cards, and advanced computing.
