IRS2541PBF Description

The IRS254(0,1) are high voltage, high frequency buck control ICs for constant LED current regulation. 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. The application is inherently protected against short circuit conditions, with the ability to easily add opencircuit protection.
