Category
Sub-Category

LM3409HV 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 5.00 A. Assuming a typical 3.5V LED forward voltage LM3409HV can drive up to 20 LED in series.

The LED Buck driver IC features adjustable 1000 kHz switching frequency, a feedback voltage of 0.25 V and requires a typical inductor size of 15.0 uH. This combination results in a peak efficiency of ~92 %. LM3409HV comes in 1 package option(s) - MSOP-10 .
