Alpha and Omega Semiconductor Limited (NASDAQ: AOSL) announced three digital multiphase controllers designed for Intel's Panther Lake and Wildcat Lake mobile processor platforms. The controllers, designated AOZ71049QI, AOZ71149QI, and AOZ71146QI, are engineered for Intel IMVP9.3 Vcore power delivery systems.

The controllers utilize what the company calls Advanced Transient Modulation technology, which combines variable-frequency hysteretic peak-current mode control with phase-current sensing. The AOZ71049QI series features configurations supporting up to 4+2+1+2 phase outputs across Core, Graphics, Auxiliary, and LPCORE domains, with quiescent current consumption of 5.9mA at PS0 for 3+2+1+1 configurations.

AOS pairs these controllers with its AOZ52986QI Smart Power Stage, housed in a 3x4 QFN package. The power stage supports 45A continuous output with peak capability of 80A, operating across a 2.7V to 22V supply range. It includes integrated current monitoring with 3.5% accuracy and temperature monitoring with 2% accuracy.

"Our AOZ71049 series provides a novel control scheme that meets Intel's most stringent requirements while delivering the lowest quiescent power in the industry," said Wayne Lee, Power IC Product Marketing Director at AOS.

The multiphase controllers are available in production quantities with 12-16 week lead times. Unit pricing in 1,000-piece quantities ranges from $2.66 to $2.75. The AOZ52986QI Smart Power Stage is immediately available with a 16-18 week lead time, priced at $1.50 per unit in 1,000-piece quantities.

The controllers support programmable configurations through Multi-Time Programmable Memory via a graphical user interface, eliminating manual solder rework during development phases according to the company's statement.
