The breadth of LED applications has grown to encompass everything from general lighting to automotive, industrial and test equipment, sign boards, and safety equipment. As a result, it's expanded the design requirements for LED drivers. Engineers must meet these requirements with high efficiency, low noise, and in a compact form factor while providing features like high dimming ratios and advanced fault protection.

So much about LEDs make them ideal for use in automotive lighting. There's a visual appeal of LED tail and daytime running lights. Efficient LED headlights are robust, with lifetimes orders of magnitude longer than their relatively burn-out-prone filament-based predecessors.
