LED Drivers


Microchip LED drivers are based on system-centric, mixed-signal LED driver technology for backlighting and solid-state lighting (SSL) applications. This broad-based and rapidly growing market includes LCD TVs, PC monitors, specialty panels (industrial, military, medical, avionics, etc.) and general illumination for the commercial, residential, industrial and government market segments. LED drivers utilize a proprietary and patented combination of analog and digital circuit techniques and power control schemes.

These products comprise a system-centric solution for local and global dimming, power management, signal conditioning and smart interfacing. This approach allows electronic equipment manufacturers to significantly enhance product features, while improving power efficiency, reliability and cost/performance.
