IRS2541 - (IRS2540 / IRS2541) LED Buck Regulator Control IC

Download the IRS2541 datasheet PDF. This datasheet also covers the IRS2540 variant, as both devices belong to the same (irs2540 / irs2541) led buck regulator control ic family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key Features

  • 200 V (IRS2540) and 600 V (IRS2541) half bridge driver.
  • Micropower startup (.

www.DataSheet4U.com Data Sheet No. PD60293 IRS254(0,1)(S)PbF LED BUCK REGULATOR CONTROL IC 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. 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.
