Versatile Boost Controller for LED/LCD Applications from Diodes Incorporated Delivers 1-100% Dimming Range
May 02 2019 - 11:00AM
Business Wire
Diodes Incorporated (Nasdaq: DIOD) today introduced the AL3353
LED/LCD 40V max input boost controller, applicable across a wide
range of applications where a constant voltage or constant current
are required to drive displays and backlights with a dimming ratio
of 100:1. It is well suited for use as a backlight driver for LCD
TVs, LCD monitors, and flat panel displays, as well as an LED
driver for commercial lighting applications.
The AL3353 is a multipurpose boost controller featuring a wide
input voltage of 9V to 40V, allowing it to easily adapt to a
variety of common supply voltages, such as 12V, 24V, and 36V,
without further configuration or loss of efficiency. The AL3353
also includes comprehensive and robust circuit protection based on
proprietary technology.
Through the implementation of Diodes’ dynamic linearity
compensation technique, which uses an offset cancellation chopping
circuit, the AL3353 maintains linearity across temperature and
process variations. This patent-pending technology accepts a
digital PWM input and converts to an internal analog signal to
control the dimming level, which operates from 1% to 100% dimming
range, or a 100:1 ratio. This is significantly wider than the
dimming range offered by most boost drivers available today
targeting this application space.
In addition to a wide input voltage range and excellent dimming
capabilities, the AL3353 features extensive protection designed
specifically for the target applications. This includes diode and
inductor short protection, LED cathode short-to-GND protection,
LED-open protection, and power MOSFET overcurrent protection. Other
protection features are under-voltage lock-out, output overvoltage
and over-temperature protection, and VOUT-short protection.
The AL3353 is available in the SO-8 package. Further information
