Its high efficiency,
current mode and fixed frequency operation ensure uniform LED brightness, low
noise and maximum battery life, while on-chip Schottky diodes eliminate both
the added cost and space requirements of external diodes. The LT3466 contains
two independent converters capable of driving asymmetric LED strings (up to10
in series per converter) from an input voltage of 2.7V to 24V, delivering
efficiencies up to 81%.
