Alpha and Omega’s New 80V and 100V MOSFETs Offer Lowest RDS(on) in Tiny DFN Package

Alpha and Omega Semiconductor Limited (AOS) announced the release of AON7280 and AON7290, the newest additions to its new 80V and 100V AlphaMOS™ medium-voltage portfolio. These new products are well suited for a wide range of applications that include secondary side synchronous rectification in dc-dc and ac-dc converters, point-of-load modules for telecom systems, and power-over-ethernet networking applications.

Built using AOS proprietary AlphaMOS technology, the 80V AON7280 and 100V AON7290 offer ultra-low RDS(on) that are 27% and 10% better than the leading competitors, respectively. The low on-resistance minimizes conduction losses and allows the device to operate at lower temperatures. This was achieved without compromising switching performance as both devices offer the lowest RDS(ON) in the industry. These solutions are packaged in a green DFN 3.3×3.3 package, giving circuit designers flexibility in board-space critical applications.

“When constructing efficient power solutions in tight spaces, designers turn to high performance MOSFETs in smaller packages,” said Stephen Chang, Sr. Product Marketing Manager at AOS. “AON7280 and AON7290 combine high density AlphaMOS technology with a compact DFN 3.3×3.3 package to meet the needs of those designers.”

Both AON7280 and AON7290 are immediately available in production quantities with a lead-time of 12-14 weeks. The unit price for 10,000 pieces of each device is $0.61.
