Alpha and Omega Semiconductor Unveils High-Performance Smart Power Stage (SPS) Family - Seite 2

“The Smart Power Stage in the QFN 5 x 6 footprint has been an industry standard for a while. AOS’s approach of offering a family of devices for various performance levels and end applications makes our offering unique. For example, our AOZ5279QI can be used for gaming laptop applications being powered by a 20V adaptor, while, our AOZ5277QI, AOZ5273QI, and AOZ5276QI offer multiple options in multiphase regulators used in add-in cards, servers, 5G and artificial intelligence,” said Peter Cheng, Sr. Director, Power IC Marketing at AOS.

Technical Highlights

The AOZ527xQI family of SPS supports both server, AI and GPU add-in card (12V input) as well as gaming laptop (20V input) input voltage operating range. Three performance levels (60A, 70A, and 90A) allow tradeoffs in the current/phase and number of phases.

• DC Operating Range: 3V to 20V for AOZ5273/6/7QI
• DC Operating Range: 3V to 25V for AOZ5279QI
• Universal standard QFN5x6 package
• Capable of up to 150A for 10us
• Capable of up to 100A for 10ms
• Full waveform Current Monitor (IMON) with better than 5% accuracy
• Temperature Monitor (TMON) with open-drain Fault reporting
• Dynamic control of OCP threshold and ZCD control
