The breadth of LED applications has grown to encompass everything from general lighting to automotive, industrial and test equipment, sign boards and safety instruments. Feature equirements for LED drivers have become more extensive. The latest LED solutions require drivers that are compact, efficient, low noise, and have high dimming ratios and advanced fault protection. The LT3922 meets these demands.

The LT3922 synchronous LED driver with integrated 2A, 40V switches can be configured as a boost, buck or boost-buck LED driver. Its high efficiency integrated switches fit into a tiny 4mm × 5mm QFN package. This device integrates Linear’s most advanced switching technologies, condensing high power capability into tight spaces while controlling the edge rates and mitigating unwanted EMI. The LT3922 features controlled switching edges that do not ring—offering just the right balance of high efficiency and low noise. They can be run at up to 2.5MHz for compact solutions.
