3 Description
The LM36011 is an ultra-small LED flash driver that
provides a high level of adjustability. With a total
solution size of 4 mm², it can produce up to 1.5 A of
LED flash current or up to 376 mA of torch current.
This is all done from a accurately programmable
current source without the need of a pre-regulated
voltage, which saves on solution size and cost.
Features of the LM36011 are controlled via an I²C-
compatible interface. These features include:
hardware flash (STROBE), flash time-out, UVLO,
thermal scale-back, LED fault detection, and 128
programmable currents for both flash and movie
mode (torch). The device operates over a –40°C to
+85°C ambient temperature range.
