DESIGN FEATURESвЂ‰L 4.5A Monolithic LED Drivers with
3000:1 Dimming are Ideal for
a Wide Range of High Power
LED Applications
by Mark W. Marosek
Introduction The LT3478 and LT3478-1 are monolithic step-up DC/DC converters
specifically designed to drive high
brightness LEDs with a constant current over a wide programmable range.
They are extremely easy to use and
include programmable features for
optimizing performance, reliability,
size and overall solution cost. These
devices can operate in boost, buckmode boost and buck-boost mode
LED driver topologies. Depending on
the topology, they can provide up to
4A of LED current, a level unmatched
by other monolithic LED drivers. The
LT3478 and LT3478-1 are ideal for
high power LED applications, including automotive and avionic lighting,
and are available in a 16-pin thermally enhanced TSSOP package with
either E-grade or I-grade temperature
ratings.
The LT3478 and LT3478-1 operate similarly to conventional current mode boost converters, but use LED …
