LвЂ‰DESIGN FEATURES LED Driver Yields 3000:1 True Color
PWM Dimming with Any Buck, Boost
or Buck-Boost Topology from a Wide
3VвЂ“40V Input Range
by Xin Qi
Introduction
High power LEDs are quickly expanding their reach as a light source for
TV projection, scanners, and various
automotive and avionic products.
All require a constant LED current,
whether in buck, boost, buck-boost
or SEPIC configurations. Pulse Width
Modulation (PWM) is the preferred
dimming method for these LED systems to preserve LED color over a wide
dynamic range of light intensities.
The LT3518 is a highly integrated
2.3A full-featured LED driver capable of providing 3000:1 True Color
PWMв„ў dimming ratio in a variety of
topologies for high power LED driver
applications.
The LT3518 features a 45V power
switch, 100mV high side current PWM PWM OSC OSC SW SW TD
TD = 200ns Figure 1. Regular LED driver timing diagram Figure 2. LT3518 timing diagram sense and accurate open LED protection. It combines a traditional voltage …
