Dear Friends,

The world is getting more and more mobile and remote, wearables and portable electronics are all around us. These devices need to run as efficient as possible, the next plug might be far away!

Find all my magazines from 2006 on in our free archive on bodospower.com. There is no better way to communicate. We all share one world. As a publisher I serve the world: one magazine, on time, every time.

Best regards,
Bodo Arlt

Alpha and Omega Semiconductor Announces World’s Lowest Quiescent Power Notebook VR Controller

The AOZ71026QI is a high-performance hybrid-digital multiphase VR controller designed in compliance with Intel IMVP 8/9/9.1/9.2 specifications. Combined with AOS high-performance DrMOS, the AOZ71026QI provides a complete power solution for Intel Alder Lake and Raptor Lake notebook platforms. AOZ71026QI supports 4+2 phases and is packaged in a 6mm x 6mm 48-pin QFN.

AOZ71026QI Benefits:

• SVID interface compliant with IMVP8, 9, and 9.1 /9.2 specifications; Supports fast Vmode
• Industry’s lowest quiescent current: 3.42 mA in PS0 for 3+2 configuration ADL-P 28W SKU
• FCCM/FCCM2 pins to lower power loss in power saving mode for notebook applications
• User-friendly GUI for compensation and configurations with minimal external RC components minimizes evaluation and development time
• ECS programmability for configurations with built-in MTP and RAM through SMBUS
• AOS Advanced Transient Modulator (A²TM) control scheme: Variable frequency hysteretic peak current mode control
• Supports industry-standard 5x5 and 3.5x4.5 DrMOS
• Acoustic noise suppression

AOZ71026QI is the world’s first multiphase controller that can meet Intel’s IMVP 9.1 notebook VR requirement of 10mW per rail. This helps increase battery life by 30 minutes to an hour in battery life workloads like full-screen video playback, web browsing, and performance benchmarks like MM14.

In addition, AOS’s proprietary A²TM control provides fast transient performance and excellent phase current balance, thus reducing BOM costs.
