Alpha and Omega Semiconductor Rolls Out Advanced Synchronous Buck Regulator Tailored for Data Communication Usage
Alpha and Omega Semiconductor Introduces New EZBuck Regulators for Intel Platforms, Now Available at BonChip Electronics
Alpha and Omega Semiconductor Limited (AOS), a leading designer, developer, and global supplier of power semiconductors, announces its latest innovation: the AOZ22559QI and AOZ22539QI Constant On-Time Buck Converters. These EZBuck regulators address the growing demand for compact and efficient power solutions in Intel's next-generation Meteor Lake and Arrow Lake platforms.
Alpha and Omega Semiconductor Limited (AOS), a prominent creator, manufacturer, and worldwide distributor of a wide array of discrete power semiconductors, wide bandgap power devices, power ICs, and power modules, has launched its new EZBuck regulators tailored for use in Intel Meteor Lake and Arrow Lake platforms. Designed with the industry's most compact QFN 4 x 4 package footprint, the AOZ22559QI and AOZ22539QI Constant On-Time Buck Converters are optimized to power the VCCPRIM_VNNAON rails in these next-gen computing architectures.
With Intel's Meteor Lake and Arrow Lake platforms requiring VCCPRIM_VNNAON rails to support substantial currents, conventional power solutions have typically banked on controllers with separate power FETs or large-footprint converters. AOS breaks the mold by packing the complete power silicon into a diminutive QFN 4 x 4 package, delivering currents of 15 A through the AOZ22559QI and 12 A via the AOZ22539QI models.
These new AOZ22559QI and AOZ22539QI Buck Converters come equipped with features critical for the Intel Meteor Lake and Arrow Lake specifications, including a fixed nominal voltage of 0.77 V across system states S0 to S5. Intel's designs also demand the solution's ability to perform remote sensing to ensure tight voltage tolerance and mitigate ground bounce effects. Meeting this challenge head-on, AOS's components have successfully navigated rigorous validation processes, confirming adherence to Intel's exacting standards. As a result, both the AOZ22559QI and AOZ22539QI have earned spots on Intel's PCL (Platform Component List), cementing their role in the VCCPRIM_VNNAON power architectures.
Additional features packed into the AOZ22559QI and AOZ22539QI include a Power Good (PGOOD) output signal, an integral bootstrap diode, and built-in soft start functionality. Their suite of protection features spans cycle-by-cycle current limiting, short-circuit protection (SCP), Overvoltage Protection (OVP), and a thermal shutdown mechanism. Furthermore, the ILIM pin is thoughtfully included to grant system designers the flexibility to modulate current limit thresholds, optimizing the balance between power inductance, output current capability, and component footprint.
