Led Buck Regulator Control Ic -

The IRS2540 IRS2541 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 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. By International Rectifier Corp.
