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.

Pricing and Availability

The AOZ23567QI is immediately available in production quantities with a lead time of 12 weeks. The unit price for 1,000-piece quantities is $2.70.
