Category
Sub-Category

ACT111A is a non-sync DC/DC Buck LED driver IC from . Maximum input voltage is 30.0 V and it drives an output current of up to 1.50 A. Assuming a typical 3.5V LED forward voltage ACT111A can drive up to 7 LED in series.

The LED Buck driver IC features fixed 1400 kHz switching frequency, a feedback voltage of 0.10 V and requires a typical inductor size of 10.0 uH. This combination results in a peak efficiency of ~92 %. ACT111A comes in 1 package option(s) - SOT23-6 .
