Description
Fully Integrated Secondary-Side Rectification Circuit Simplifies Design and Improves Efficiency
The iW873 secondary-side synchronous rectification solution works with several of Renesas' primary-side controllers to deliver the high efficiency needed for high-power-density smartphone and tablet power adapters.
The iW873 integrates a 60V power MOSFET with Renesas' proprietary digital adaptive turn-off control technology to replace the secondary-side Schottky diode with a MOSFET for higher power density adapters. It also uses adaptive control to minimize dead-time, eliminating the need for a parallel Schottky diode required by conventional synchronous rectifier solutions.
A DiaSIM™ simulation model is available for the iW673. For more information and where to download, please visit the DiaSIM page.
