They incorporate a continuous mode time-delayed hysteretic buck regulator to directly control the average load current, using an accurate on-chip bandgap voltage reference. These parts directly replace the IRS2540 and IRS2541 with improved latch up immunity. 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 lowside driver is also provided for synchronous rectifier designs. All functions are realized within a simple 8 pin DIP or SOIC package. www.irf.com © 2010 International Rectifier 3 Free Datasheet http://www.datasheet4u.com/ IRS254(01,11)(S) Alternate application circuit using a single MOSFET IRS25401 www.irf.com © 2010 International Rectifier 4 Free Datasheet http://www.datasheet4u.com/ IRS254(01,11)(S) Qualification Information Qualification Level † Moisture Sensitivity Level Machine Model ESD Human Body Model IC Latch-Up Test RoHS Compliant † †† ††† Industrial†† Comments: This family of ICs has passed JEDEC’s Industrial qualification.
