Highly Flexible, Small High-Power LED Driver Can Drive Up to 8 HB LEDs

The ISL78100 is very flexible and can be configured to optimally drive from one to eight HB (high brightness) LEDs, while being capable of operating in boost, buck or SEPIC configurations, and thereby is up to 92 percent efficient. The ISL78100 also features two methods of controlling LED light level; a DC bias current, or through the use of an external PWM signal for more accurate control of the LED color temperature.

In addition, there are optional integrated protection features that the designer can choose from with the ISL78100. An available fault monitor that disconnects the input supply can be used to protect against load dump conditions.

The ISL78100 also features thermal compensation and a load isolation switch. The device’s temperature compensation drastically improves LED lifespan and an integrated over-temperature control circuit monitors a thermistor voltage and adjusts the LED bias current. This high level of integration allows designers to avoid the use of costly discrete protection solutions.

The device is both AEC-Q100-rated and fully TS16949-compliant, including a higher process CPK. The ISL78100 is rated for the automotive temperature range (-40° C to +105° C) and, with a tiny 4mm x 4mm x 0.9mm QFN package, is the smallest integrated high power LED driver available.

Pricing and Availability:
The ISL78100 is available now in a 20-lead QFN package and is priced at $1.32 in 1,000-unit quantities and at $1.39 in 1,000-unit quantities in tape-and-reel configurations. More information on the ISL78100 is available at http://www.intersil.com/cda/deviceinfo/0,1477,ISL78100,0.html
