PRELIMINARY

High Power LED Driver

Features

The EL7801 is a high-power LED backlight driver with an

integrated 36V FET designed to drive up to 8 high-power

LEDs in series while running from a 12V input supply. 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 1 to 8 series diodes to be

driven from a 12V input.

• Drives 1-8 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

• PWM/analog light level control

ENABLE/PWM pin.

• Small, 20 Ld 4mm x 4mm QFN package

• Pb-free plus anneal available (RoHS compliant)

In both control modes optional over temperature thermal

protection of the LED reduces the LED DC bias current

above a customer 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.

Applications

• Display backlighting

- Automotive

- LCD monitor

- Notebook displays

• LED accent lighting

• Automotive lighting

The EL7801 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.

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.
