LT3597 Buck LED driver IC overview
LT3597 is a non-sync DC/DC Buck LED driver IC from . Maximum input voltage is 60.0 V and it drives an output current of up to 0.10 A. Assuming a typical 3.5V LED forward voltage LT3597 can drive up to 10 LED in series.
The LED Buck driver IC features adjustable 1000 kHz switching frequency, a feedback voltage of 1.22 V and requires a typical inductor size of 100.0 uH. This combination results in a peak efficiency of ~80 %. LT3597 comes in 1 package option(s) - QFN-52 .
