Category
Sub-Category

LM3404HV is a non-sync DC/DC Buck LED driver IC from . Maximum input voltage is 75.0 V and it drives an output current of up to 1.20 A. Assuming a typical 3.5V LED forward voltage LM3404HV can drive up to 18 LED in series.

The LED Buck driver IC features adjustable 400 kHz switching frequency, a feedback voltage of 0.20 V and requires a typical inductor size of 47.0 uH. This combination results in a peak efficiency of ~96 %. LM3404HV comes in 2 package option(s) - SO-8 PSOP-8 .
