SUNNYVALE, Calif.--(BUSINESS WIRE)-- Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL), 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.
• Power Distribution Board for AI Datacenters (Power MOSFETs): AOS is showcasing an application-specific MOSFET AOTL66935 for 48V Hot Swap with High Safe Operating Area (SOA) in TOLL package, and soon available in LFPAK8x8 (AOLV66935). AOTL66935 and AOLV66935 have ultra-low RDS(on) (<1.9mOhm) and high junction temperature ratings at 175°C. AOS designed these MOSFETs with low on-state resistance and robust linear mode performance to protect AI servers and telecom equipment where performance, reliability, and quality are essential.
• High Power Motor Drive Applications: AOS has developed state-of-the-art package options for its industry-leading MOSFET portfolio. Designed to meet the increasing performance and reliability application demands, the LFPAK, GTPAK™, and GLPAK™ packages combined with AOS’ MOSFET technology deliver low ohmic, low parasitic inductance, and high current capability advantages. These packages also feature gull-wing leads, offering a rugged solution for board-level environmental stresses. These features offer key benefits in reducing losses, improving power density, lowering EMI, and enhancing board-level reliability for key applications such as e-mobility, battery management, and other high-current applications. The GTPAK offered with the AOGT66909 is designed to mount a heatsink with a large exposed pad on the package surface. The topside cooling technology effectively transfers most heat to the heatsink instead of PCB, dissipating heat more efficiently. The GLPAK offered with the AOGL66901 is designed to achieve a high inrush current rating using AOS' advanced clip technology. The Gull-wing design enhances board-level reliability. The GLPAK with clip technology offers very low package resistance and parasitic inductance, improving EMI performance compared to other package types that employ standard wire bonding.
