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 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.
Features
• 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
• Small 8-Lead DIP/8-Lead SOIC packages
Functional Equivalent (FE) materials, including Fused Filament Fabrication (FFF) form, assembly, and functionally compatible substitute materials.
