PD60293 IRS254(0,1)(S)PbF LED BUCK REGULATOR CONTROL IC Description 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 opencircuit 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 realize...
