Our expert contributors provide a complete, detailed view of partial HDI this month. Most experienced PCB designers can start using this approach right away, but you need to know these tips, tricks and techniques first.
Silicon to Systems: From Soup to Nuts
This month, we asked our expert contributors to weigh in on silicon to systems—what it means to PCB designers and design engineers, EDA companies, and the rest of the PCB supply chain... from soup to nuts.
Cost Drivers
In this month’s issue of Design007 Magazine, our expert contributors explain the impact of cost drivers on PCB designs and the need to consider a design budget. They discuss the myriad design cycle cost adders—hidden and not so hidden—and ways to add value.

Alpha, Omega Semiconductor Announces Application-Specific EZBuck™ Regulator Designed to Power Intel Arrow Lake Platform
October 9, 2024 | AlphaEstimated reading time: 2 minutes
Alpha and Omega Semiconductor Limited (AOS), a designer, developer, and global supplier of a broad range of discrete power devices, wide band gap power devices, power management ICs, and modules, announced its new application-specific EZBuck™ Regulator. The highly integrated, compact, and high-power-density AOZ23567QI Constant On-Time Buck Converter offers an upgraded solution that is designed to support VCCPRIM_VNNAON rails in the Intel Arrow Lake platform.
Intel’s Arrow Lake S Line platform requires VCCPRIM_VNNAON rails with high currents. These high-current rails are typically supported by power implementations that require either a controller with external discrete power FETs or a converter with a large package. AOS’ AOZ23567QI Constant On-Time Buck Converter delivers a highly integrated, high-power-density solution that includes all necessary power silicon in a thermally enhanced QFN 5 x 5 package. The device is capable of providing 22A continuous and 45A peak current capability.
Specifically designed to meet the specifications of the Intel Arrow Lake S Line platforms, the AOZ23567QI features a nominal fixed voltage of 0.77V, which is supplied in system states of S0 through S5. Intel also requires power regulation capable of remote sensing to maintain accurate tolerance and account for ground bounce. AOS’ AOZ23567QI has passed all the validation requirements through stringent tests to ensure compliance with Intel specifications. In addition, Intel has approved the AOZ23567QI as a key component on their PCL (Platform Component List) for VCCPRIM_VNNAON power architectures.
Helping to increase reliability, the AOZ23567QI also features 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. In addition, the EZBuck™ Regulator’s LIM 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.
Key Features
- Supports Intel Arrow Lake platform remote sensing with a nominal 0.77V output voltage
- Wide input voltage range: 4.5V to 28V
- High Current Capability: 22A continuous and 45A Peak current capability to support Intel Iccmax events
- Low RDS(ON) internal NFETs: 5mOhm HS FET, 1.8mOhm LS FET
- Adjustable current limit setting
- Thermally-enhanced 5 x 5 QFN package
“The AOZ23567QI offers designers a feature-rich, high-current solution for VCCPRIM_VNNAON rails, providing optimal power support for the Intel Arrow Lake platforms. PCB real estate is at a premium in today’s ever-shrinking mobile laptop form factors. Utilizing AOS’ advanced EZBuck™ technology, the AOZ23567QI delivers a highly integrated yet very compact buck converter that efficiently and effectively solves the system designer’s continual space-constrained challenges,” said Wayne Lee, Sr. Marketing Manager, EZBuck™ Product Line at AOS.
