LвЂ‰DESIGN IDEAS No PWM Signal Needed for Accurate
Dim/Bright Control of Automotive
Brake Lights and Other Signal LEDs
Introduction by Bill Martin LEDs are quickly becoming standard
lighting for a variety of commercial,
automotive, and industrial applications. Some of these applications
require wide-range brightness control,
spurring a demand for products that
offer PWM-based LED brightness
control. However, many applications
only require two settings, bright and
dim, so generating a PWM signal for a
binary choice is inconvenient overkill.
The LT3592 LED driver is the solution
to this problem. It simplifies design
by offering two LED current settings
with a 10:1 ratio, selected via a simple
digital control pin. This pin has a low
threshold voltage, but high voltage
capability, making it very easy to
plug into any automotive or industrial
system. For an application such as
automotive brake light control, the …
