Backlight LED drivers

High-performance drivers for a wide variety of screen sizes

Our large portfolio of step-up (boost) LED drivers utilize global dimming techniques for LCD backlighting. You are able to use a single-channel option with up to 90% efficiency or maintain the same LED count and use a higher-channel count option to improve total system efficiency. Our backlight LED drivers extend your LED’s life with a range or protection features and optimize LCD screen performance with high-dimming and contrast ratios.
