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.

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.

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.

Key Features

• Supports Intel Meteor Lake and Arrow Lake platform remote sensing with a nominal 0.77V output voltage
• Wide input voltage range: 5.5V to 25V
• High Current Capability: 15A supporting Intel Itdc and 30A supporting Intel Iccmax
• Low RDS(ON) internal NFETs: 11mOhm HS FET, 4mOhm LS FET
