40V 0.99mOhm MOSFET in a DFN5x6 Package

December 21, 2014 by Jeff Shepard

Alpha and Omega Semiconductor Limited (AOS) announced the release of AON6590, the flagship device in its new 40V medium voltage portfolio. The AON6590 is designed to address a wide range of applications including primary-side and secondary-side switching in telecom and industrial dc-dc converters, secondary-side synchronous rectification in dc-dc and ac-dc converters, as well as point-of-load modules for telecom systems.

The AON6590 is the lead product in what will be a new portfolio of 40V products that are optimized for switching power conversion. Compared to previous generations, this new product improves on-resistance by 30% which reduces conduction losses and allows lower case temperatures during heavy load operation. AON6590 also offers low output capacitance, reducing turn-off energy loss, thus enabling higher efficiencies in hard-switched applications. In addition to the performance benefits, this device has been designed with a robust UIS capability to handle extreme conditions such as output short circuits or start-up phases. The AON6590 is available in a compact DFN5x6 power package.

"AON6590 marks a new generation of products designed to enable rugged system solutions with higher power density. The new device allows our customer to design power supplies that run cooler and improve overall system reliability." said Stephen Chang, Sr. Product Marketing Director at AOS.

AON6590 technical highlights include: 40V N-channel MOSFET in a DFN5x6 package; RDS(ON) < 0.99 mOhms maximum at VGS = 10V; RDS(ON) < 1.5 mOhms maximum at VGS = 4.5V; COSS = 1438 pF typical; Qg (10V) = 100 nC typical; and 100% Rg and UIS tested . The AON6590 is immediately available in production quantities with a lead-time of 12-14 weeks. The unit price for 10,000 pieces is $1.11.
