IRS254(0,1)(S)PbF  
LED BUCK REGULATOR CONTROL IC  
Description  
Features  
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.  
200 V (IRS2540) and 600 V (IRS2541) half bridge  
driver  
Micropower startup (<500 µA)  
±2% voltage reference  
140 ns deadtime  
15.6 V zener clamp on VCC  
Frequency up to 500 kHz  
Auto restart, non-latched shutdown  
PWM dimmable  
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.
