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
with improved latch up immunity.
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.
