3 Description

The LM36011 is an ultra-small LED flash driver that

provides a high level of adjustability. With a total

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.

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.
