This is a Boost LED driver designed drive white LED with constant current. It can drive 2 ~ 6 LED in a series connection from a single Li-Ion cell ensuring uniform brightness in small screen backlighting applications. The device also supports a single feedback of parallel connected multiple strings of LEDs for driving higher number of LEDs. It is available in SOT26, low profile TSOT26 and the extremely thin and small footprint U-DFN2020-6 Type C.
