FEATURES
LT3003
3-Channel LED
Ballaster with PWM
DESCRIPTION
The LT
®
3003 drives three separate strings of LEDs up
to 350mA/channel with 3% accurate current matching,
resulting in uniform LED brightness and intensity. This
approach is superior to conventional methods of running
three separate channels with external ballast resistors
requiring expensive factory calibration.
The LT3003 operates in boost, buck and buck-boost mode.
A True Color PWM Dimming ratio of up to 3000:1 is achiev-
able using a logic-level signal at the PWM pin for all modes
without the need for external level-shifting circuitry. For
applications with input supply above and below the output
voltage of the LED strings, the LT3003 allows the LEDs to
be returned to the input supply (buck-boost mode) instead
of being limited to only SEPIC solutions.
The LT3003 is ideal for high power LED driver applications
such as TFT LCD backlighting and heads-up displays. Ad-
ditional overtemperature outputs allow appropriate system
management for increased reliability.
The LT3003 is available in a small 10-pin MSE package.

I find that even with the development of the Internet, there are still books that are not available or difficult to buy.
So depressed... I've looked at Joyo and Dangdang, but can't find it. I guess it's because it's not selling well. Business comes first... :Q :Q :Q :'( :'( :'( I'll look for it tomorrow......
