AOZ22559QI 和 AOZ22539QI 是具有恒定导通时间控制（COT控制模式）的同步降压转换器，为 Intel Meteor Lake 和 Arrow Lake CPU VCCPRIM_VNNAON 电源提供最高功率密度解决方案......

SUNNYVALE, Calif., Feb. 22, 2024 – Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL), a designer, developer, and global supplier of a broad range of discrete power devices, wide band gap power devices, power management ICs, and modules, today introduced its new application-specific EZBuck™ regulator. The AOZ22559QI and AOZ22539QI Constant On-Time Buck Converters are offered in a QFN 4 x 4 package, which is the industry’s most compact footprint and is designed to support VCCPRIM_VNNAON rails in Intel Meteor Lake and Arrow Lake platforms.

日前，集设计、研发、生产和全球销售一体的著名功率半导体、芯片及数字电源产品供应商Alpha and Omega Semiconductor Limited（AOS，纳斯达克代码：AOSL）推出了全新的应用导向 EZBuck™ 转换器。 AOZ22559QI 和 AOZ22539QI是应用恒定导通时间控制的降压转换器。采用了业界最紧凑的 QFN 4 x 4 封装，旨在支持 Intel Meteor Lake 和 Arrow Lake 平台中的 VCCPRIM_VNNAON电源应用。

Intel’s Meteor Lake and Arrow Lake platforms require VCCPRIM_VNNAON rails with high currents, whereas supporting power implementations typically require either a controller with external discrete power FETs or a converter with a large package. In contrast, AOS’s highly integrated solution includes all 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.

Intel Meteor Lake 和 Arrow Lake 平台需要具有支持高电流的 VCCPRIM_VNNAON 电源，而为了实现高电流输入，传统的电源架构是使用电源控制器搭配独立的功率MOSFET，或使用较大封装的同步降压转换器。相比较之下，AOS高度集成方案（如AOZ2263VQI可实现QFN 4 x 4封装支持持续12A）可以最大限度地减少整体设计空间，从而实现出色的功率密度。AOS 应用恒定导通时间控制的高度集成解决方案在单个 QFN 4 x 4 封装中包含所有必需的电源芯片（AOZ22559QI 支持持续15A 电流；AOZ22539QI支持持续12A 电流）。

The AOZ22559QI and AOZ22539QI include features specifically designed to meet the specifications of the Intel Meteor Lake and Arrow Lake platforms. They have 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. 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.

AOZ22559QI 和 AOZ22539QI 两款同步降压转换器专为满足 Intel Meteor Lake 和 Arrow Lake 平台电源规范而设计研发。其额定固定电压为 0.77V，并在 S0 到 S5 的不同系统工作模式下供电。 Intel还要求该解决方案能够进行遥感，以保持准确的容差并避免接地反弹。AOZ22559QI 和 AOZ22539QI 经过严谨且高规格要求的测试并通过了所有验证要求，确保符合Intel规范。此外，AOZ22559QI 和 AOZ22539QI 已列入其官方 VCCPRIM_VNNAON 电源架构建议用料名单（ PCL）里。

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.

AOZ22559QI 和 AOZ22539QI 内部集成包括 Power GOOD 输出、自举二极管和软启动等。其保护功能包括每周期过电流限制侦测、输出短路保护 (SCP)、输出过压保护 (OVP) 和过温保护。ILIM pin还可支持调整电流限制，从而平衡输出功率扼流圈、输出电流能力和组件尺寸。
