Low EMI LED Driver with Synchronous Internal 2A Switches

Keith Szolusha - Applications Engineering Section Leader Nov 17th 2016

The LT3922 40V, synchronous, Silent Switcher low EMI LED driver meets the demands of the next generation of LED systems.

These LED drivers require more features and higher performance than ever before. Higher efficiency prolongs battery life and reduces heat in space-constrained applications. Wide voltage ranges are needed to accommodate the many sources of energy and combinations of LEDs. Automotive converters must have low EMI. High PWM dimming ratios are needed for day and night display brightness control. Long off-times are needed between PWM pulses for machine vision and camera flashes. And all of these need the most advanced fault protection with the least number of components possible.
