AOZ2264VQI and AOZ2369VQI with Adjustable
Output Voltage using 2-bit VID Provides Highest Power Density
Solution for Intel Tiger Lake CPU VCCIN_AUX Rails
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
introduced a new family of application-specific EZBuck™ regulators.
The AOZ2264VQI and AOZ2369VQI are offered in a QFN 4 x 4 and QFN 5
x 5 package, respectively, and offer the industry’s most compact
footprint to support VCCIN_AUX rails in Intel Tiger Lake platforms
used in notebook and desktop computing systems.

Intel’s Tiger Lake platform consists of two rails; one rail
powers the core and graphics processors, and the other, known as
VCCIN_AUX, powers the auxiliary processor. The auxiliary processor
supports add-on features in personal computing systems such as
audio, video, connectivity, and other functions that enhance user
experience. Feature-rich personal computing systems require a
VCC_AUX rail with high currents. Typical competitor power
implementations require either a controller with external discrete
power FETs or a dual-phase converter. These solutions require more
board space than AOS highly integrated solution that includes all
the power silicon in a single QFN 4 x 4 package for 16A and QFN 5 x
5 package for 30A.
Technical Highlights
The AOZ2264VQI and AOZ2369VQI converters include features
specifically designed to meet the specifications of the Intel Tiger
Lake Platform. The 2-bit VID pins allow the VCCIN_AUX power rail to
adjust with voltage for 0V, 1.1V, 1.65V, and 1.8V depending on
multiple systems operating modes. Both devices have also passed all
the validation requirements included in the Intel Tiger Lake
Platform Component List (PCL). This test puts the regulator through
stringent tests to ensure compliance with Intel specifications.
AOS’s proprietary COT architecture provides ultra-fast load
transient response performance and enables stable and low voltage
ripple operation with small-sized ceramic capacitors, further
reducing solution size and cost.
Key Features
- Wide input voltage range: 4V to 28V
- High Current Capability 16A: AOZ2264VQI, 30A: AOZ2369VQI
- Supports Intel Tiger Lake Platform 2 bits VID
- Low RDS(ON) internal NFETs
- AOZ2369VQI features a 5mOhm HS FET and a 1mOhm LS FET
- Constant On-Time with input feed-forward
- Ripple Reduction at light load
- Ceramic capacitor stable
- Fixed soft start
- Power Good output
- Integrated bootstrap diode
- Cycle-by-cycle current limit
- Short-circuit protection
- Overvoltage protection
- Thermal shutdown
- Thermally enhanced 4 x 4 QFN package for AOZ2264VQI and 5 x
5QFN for AOZ2369VQI
“The two current capabilities offered by the AOZ2264VQI and the
AOZ2369VQI offer designers a scalable solution to support Intel
Tiger Lake’s multiple platform SKUs such as UP3, UP4, and H-Line.
In state-of-the-art laptops, the system board has shrunk
considerably to make way for system fans for thermal management or
larger batteries to improve battery life. Form factors for personal
computers are always shrinking. Utilizing AOS’s EZBuck regulator
platform technology enables AOS to solve the system designer’s
problem of ever-shrinking PCB real estate,” said Wayne Lee, Power
IC Marketing at AOS.
Pricing and Availability
The AOZ2264VQI is immediately available in production quantities
with a lead-time of 12 weeks. The unit price for 1,000 pieces is
$1.129 for the AOZ2264VQI and $1.69 for the AOZ2369VQI.
