MBI6660 Buck LED driver IC overview
Description
MBI6660 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 0.50 A. Assuming a typical 3.5V LED forward voltage MBI6660 can drive up to 16 LED in series.
The LED Buck driver IC features fixed 400 kHz switching frequency, a feedback voltage of 0.10 V and requires a typical inductor size of 68.0 uH. This combination results in a peak efficiency of ~97 %. MBI6660 comes in 2 package option(s) - SOP-8 TO252-5 .
