RT6010 Buck LED driver IC overview
Description
RT6010 is a non-sync DC/DC Buck LED driver IC from . Maximum input voltage is 450.0 V and it drives an output current of up to 0.10 A. Assuming a typical 3.5V LED forward voltage RT6010 can drive up to 100 LED in series.
The LED Buck driver IC features adjustable 300 kHz switching frequency, a feedback voltage of 0.50 V and requires a typical inductor size of 4700.0 uH. This combination results in a peak efficiency of ~95 %. RT6010 comes in 1 package option(s) - SOP-16 .
