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 …
