4+2 Intel IMVP 9.1/9.2 Hybrid Digital
Multiphase Controller for Intel Alder Lake and Raptor Lake Notebook
Platforms
Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL), a
designer, developer, and global supplier of a broad range of power
semiconductors, power ICs, and digital power products, today
announced the release of the AOZ71026QI, a 2 rail, 6 phase
controller for notebook Vcore power delivery. The new device
features the world’s lowest quiescent power for a multiphase
controller designed to meet Intel IMVP 8, 9, 9.1, and 9.2
specifications. Combined with AOS’s benchmark DrMOS power stages,
the AOZ71026 provides a complete power solution for Intel Alder
Lake and Raptor Lake Notebook platforms.

AOS’s Hybrid Digital approach enables the best of both worlds:
the flexibility/tunability of a digital solution and the low
quiescent power of an analog solution. This unique approach enables
low quiescent power consumption in all power states as defined by
the Intel IMVP 9.1 platform specification to maximize battery life.
At the same time, customer or application-specific tuning or
configuration settings can be programmed into the parts register
settings via a SMBus digital interface. This minimizes system
components and eliminates manual solder re-work during the
development phase. Programmability can be done either by AOS GUI or
customized ECS into the controller’s built-in RAM. The controller
also provides MTP to store register settings once the configuration
is finalized.
The AOZ71026 provides two output rails in flexible 4/3/2/1 and
2/1 phase configurations. An SVID interface supports three separate
SVID domains: Up to 4 phases for the core voltage domain (IA) and 2
phases for the graphics voltage domain (GT), as well as the PSYS
domain’s reporting functions. The new device offers a novel AOS
Advanced Transient Modulation (A2TM). It combines an advanced
variable frequency hysteretic peak current mode control with a
proprietary phase current sensing scheme for fast transient
response and optimal current balance for both transient and DC
loads. The control loop enhances light-load efficiency by
seamlessly entering DCM mode of operation.
The AOZ71026QI provides complete protection and warning
functions, including UVP, OVP, OCP, and OTP. Fault protection
behavior can be easily programmed through SMBus. AOZ71026QI also
offers real-time telemetry information via SMBus for VIN, VOUT,
temperature, output currents, power states, as well as PSYS / VSYS
/ IAUX pins reporting via SMBus.
“The biggest challenge for multiphase VR controllers for core
power in mobile applications is how to lower quiescent power while
still providing fast and reliable performance. The AOZ71026 checks
all the boxes, offering a novel control scheme to meet stringent
power delivery requirements minimum external components thanks to
registering programmable tuning and configuration, and the
industry’s lowest quiescent power. This low quiescent power sets
its world apart from what is available in the industry. Laptops
designed using the AOZ71026 will offer from 30 minutes to 1 hour
longer run times in battery life workloads compared to competing
solutions,” said Lu Jian (LJ), Client Computing Solution Senior
Marketing Director at AOS.
