Photo Release -- Alpha and Omega Semiconductor Offers Dual-Channel EZPower(TM) Smart Load Switch Delivering up to 6A Per Channel of Continuous Current

May 06, 2014

SUNNYVALE, Calif., May 6, 2014 (GLOBE NEWSWIRE) -- Alpha and Omega Semiconductor Limited (AOS) (Nasdaq:AOSL), a designer, developer and global supplier of a broad range of power semiconductors and power ICs, today introduced AOZ1331, the latest addition to the EZPower Smart Load Switch family that delivers up to 6A per channel of continuous current. The dual device's low on-resistance of 20mohm in a thermally enhanced 3mm x 2mm DFN package give it an ideal RDS(ON)-to-footprint ratio to enhance performance in space constrained applications. The AOZ1331 is an ideal solution for the latest notebook PCs, Ultrabooks, tablets, set-top-boxes, solid-state drives, networking equipment, LCD TVs, and other consumer electronics applications.

The AOZ1331 includes two n-channel MOSFETs with an input operating voltage range of 0.8V to 5.5V, with an input bias voltage range of 2.5V to 5V. Each load switch operation is independently controlled via a low-voltage logic control signal. The device can switch 6A per channel of continuous current with a turn-on slew rate that can be programmed by an optional external capacitor. Additionally, an internal 220ohm load resistor is integrated into each channel to allow for quick discharging of capacitive output loads.

"The combination of low on-resistance and a thermally enhanced 3x2mm DFN package, allows the AOZ1331 to offer industry-leading performance, making it the ideal load switch for a variety of applications," said Daniel Chang, Vice President of the Power IC Product Line at AOS. "The AOZ1331 simplifies designs by including features such as slew rate control and load discharge that eliminate input supply glitches and other noise."
