LED Buck

SP7600 is a non-sync DC/DC Buck LED driver IC from . Maximum input voltage is 29.0 V and it drives an output current of up to 2.00 A. Assuming a typical 3.5V LED forward voltage SP7600 can drive up to 6 LED in series.

The LED Buck driver IC features fixed 1200 kHz switching frequency, a feedback voltage of 0.20 V and requires a typical inductor size of 4.7 uH. This combination results in a peak efficiency of ~96 %. SP7600 comes in 1 package option(s) - SO-8 .
