The 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’ high performance DrMOS and SPS power stages utilizing AOS’ 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’ 5 x 5 DrMOS power stages were shown to dissipate 14W lower power loss during these peak current events.
The 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’s automatic phase management (APM) and auto discontinuous mode (DCM) power saving features extend its usability to graphics cards and gaming laptops.
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 ability to update configuration in the field, and to pre-program up to six configuration settings with a pin-strap selection.
“AOS 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.
