© 2010 International Rectifier 2 Free Datasheet http://../ IRS254(01,11)(S) Description The IRS254(01,11) 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. These parts directly replace the IRS2540 and IRS2541...
