Alpha and Omega has developed an application-specific buck regulator for Intel’s Meteor Lake and Arrow Lake processors.

The AOZ22559QI and AOZ22539QI EZBuck regulators are Constant On-Time Buck Converters to support the currents required by the VCCPRIM_VNNAON rails of the Meteor Lake and Arrow Lake processors.

The Meteor Lake and Arrow Lake platforms require VCCPRIM_VNNAON rails with high currents of 15A to 30A, whereas supporting power implementations typically require either a controller with external discrete power FETs or a converter with a large package.

The highly integrated buck converters include all the necessary power silicon in a single QFN 4 x 4 package, providing 15A in the AOZ22559QI and 12A in the AOZ22539QI Constant On-Time Buck Converters.

The AOZ22559QI and AOZ22539QI include features specifically designed for Meteor Lake and Arrow Lake with a nominal fixed voltage of 0.77V and are supplied in system states of S0 through S5. Intel also requires this solution to be capable of remote sensing to maintain accurate tolerance and account for ground bounce. 

The AOZ22559QI and AOZ22539QI also feature a PGOOD output, an integrated bootstrap diode, and an integrated soft start. Protection features include cycle-by-cycle current limit, short-circuit protection (SCP), Overvoltage Protection (OVP), and thermal shutdown. The ILIM pin allows system designers to adjust current limit levels, enabling them to balance the power choke to the output, the output’s current capability, and the component size.

The internal NFETs have an RDS(on) on resistance of 11mOhm for the high side FET and  4mOhm for the low side FET with adjustable current limit settings.

AOS’s AOZ22559QI and AOZ22539QI have passed all the validation requirements through stringent tests to ensure compliance with Intel specifications. In addition, Intel approved both the AOZ22559QI and AOZ22539QI as key components on their PCL (Platform Component List) for the VCCPRIM_VNNAON power architectures.

“The AOZ22559QI and AOZ22539QI offer designers an easy-to-use high-current solution for VCCPRIM_VNNAON rails, providing optimal power support for the Intel Meteor Lake and Arrow Lake platforms. In today’s ever-shrinking mobile laptop form factors, PCB real estate is at a premium. Utilizing AOS’s EZBuck technology delivers a highly integrated and feature-rich buck converter that efficiently and effectively solves the system designer’s continual space-constraint challenges,” said Wayne Lee, Sr. Marketing Manager, EZBuck Product Line at AOS.

The AOZ22559QI and AOZ22539QI are immediately available in production quantities with a lead time of 12 weeks. The unit price for 1,000 pieces is $1.4 for the AOZ22559QI and $1.3 for the AOZ22539QI.
