ISL97801 High Power LED Driver NOT RECOMMENDED FOR NEW DESIGNS RECOMMENDED REPLACEMENT PART ISL97634 DATASHEET FN6428 Rev 1.00 April 2, 2007 The ISL97801 is a high-power LED backlight driver with an integrated 36V FET designed to drive up to 8 high-power LEDs in series.

The PWM converter runs from an internally generated 1MHz clock.

With efficiencies over 90% the regulator provides tight control of LED current and may be configured in either boost or buck topologies, allowing from 3 to 8 seri
