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.
