Exar XRP7613 Step-Down High Brightness LED Driver
Exar's XRP7613 Step-Down High Brightness LED Driver is a non-synchronous step-down converter with an integrated FET optimized to drive high power LEDs at up to 1.2A of continuous current. A wide 7.0V to 36V input voltage range allows for single supply operations from industry standard 12V, 18V or 24V power rails. Based on a hysteretic PFM control scheme, the XRP7613 can operate at switching frequency up to 1MHz and allows for small external components selection while providing very fast transient response and achieving excellent efficiency. Typical applications include general lighting and displays, architectural and accent lighting, medical and industrial instrumentation, and video projectors.
