100V Controller Drives High Power LED Strings from Just about
Any Input вЂ“ Design Note 461
by Keith Szolusha
Introduction
Strings of high power solid-state LEDs are replacing
traditional lighting technologies in large area and high
lumens light sources because of their high quality light
output, unmatched durability, relatively low lifetime cost,
constant-color dimming and energy efп¬Ѓciency. The list of
applications grows daily, including LCD backlights and
projection, industrial and architectural lighting, automotive lights, streetlights, billboards and stadium lights.
As the list expands, so does the range of VIN for the LED
drivers. LED drivers must be able to handle wide ranging
inputs, including transient voltages of automotive batteries, a wide range of other batteries and wall wart voltages.
For LED lighting manufacturers, applying a different LED
driver for each application means stocking, testing and
designing with a number of controllers. It would be better
to use just one that can be applied to many solutions.
The LT3756 high voltage LED driver features a unique
topological versatility that allows it to be used in boost,
buck-boost mode, buck mode, SEPIC, п¬‚yback and other
topologies. Its high power capability provides potentially
hundreds of watts of LED power over a wide input voltage range. Its 100V п¬‚oating LED current sense inputs provide …

As the number of applications expands, so does the complexity of input
requirements for the LED drivers.

LвЂ‰DESIGN IDEAS DonвЂ™t Want to Hear It? Avoid the
Audio Band with PWM LED Dimming
at Frequencies Above 20kHz by Eric Young
Introduction
The requirements of LED drivers become more demanding as application
designers exploit the unique characteristics of LEDs. Linear Technology offers
a complete portfolio of LED drivers
with the performance levels required to
meet even the most challenging design
requirements. One area where these
LED drivers especially excel is in the
performance and flexibility of their
PWM dimming capabilities. LEDs can
be turned on and off rapidlyвЂ”it takes
only nanoseconds to illuminate or
extinguish the source. PWM dimming
exploits this characteristic to achieve
orders of magnitude dimming, even
while maintaining a constant output
spectrum over the entire dynamic light
intensity range.
The broad field of available LED
drivers narrows quite a bit when …
