Ultra-Low on-Resistance and Robust Switching Performance Enable More Compact Power Designs
Alpha and Omega Semiconductor Limited (AOS) announced the release of AON6590, the flagship device in its new 40 V 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 POL modules for telecom systems.
The AON6590 is the lead product in what will be a new portfolio of 40 V 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 DFN 5×6 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.
