IRS25411STRPBF
The IRS25411S is a high voltage, high frequency buck control ic for constant LED current regulation. The IRS25411S incorporates 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 internal high-side bootstrap circuit drives the buck switching element at high frequencies. A low-side driver is also provided for sychronous rectifier designs. All functions are relaized with a simple 8-pin SOIC package.
