... The application is inherently protected against short circuit conditions, with the ability to easily add open-circuit protection. An external high-side bootstrap circuit drives the buck switching element at high frequencies. A low- side driver is also provided for synchronous rectifier designs. All functions are realized within a simple 8 pin DIP or SOIC package. www.irf.com IRS254(01,11)(S) 3 © 2010 International Rectifier ...
