High Power LED Driver

Features

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 series diodes to be driven from wide input voltages.

• Drives 3-8 high-power LEDs in series, up to 32V

• 2.7V to 16V input voltage range

• Boost or Buck configurable switch

• 3A integrated FET

• Automotive load dump protection

• Light output temperature compensation

• LED over-temperature protection

• LED disconnect

LED light level may be controlled either by:

1. LED DC bias current set via the LEVEL pin, or

2. External low frequency PWM control via the

ENABLE/PWM pin.

• PWM/analog light level control

In both control modes optional over temperature thermal

protection of the LED reduces the LED DC bias current

above an adjustable set temperature, protecting the LED

from thermal damage. An optional fault monitor drives an

external FET between the input supply and inductor,

providing short circuit current protection for the LED and

inductor as well as load dump protection for automotive

applications. For low cost applications the pass transistor

may be omitted and the fault pin bypassed.

• Small, 20 Ld 4mm x 4mm QFN package

• Pb-free plus anneal available (RoHS compliant)

Applications

• Display backlighting

- Automotive

- LCD monitor

- Notebook displays

The ISL97801 is packaged in a 20 Ld 4mm x 4mm QFN

package and is specified for operation over the -40°C to

+105°C temperature range.

• LED accent lighting

• Automotive lighting

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
