Inductorless single-LED flash driver offers a high level of adjustability

The LM36011 from Texas Instruments, is an ultra-small LED flash driver that provides a high level of adjustability. With a total solution size of 4mm2, it can produce up to 1.5A of LED flash current or up to 376mA of torch current. This is all done from an accurately programmable current source without the need of a pre-regulated voltage, which saves on solution size and cost. The device features 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 –40C to +85C ambient temperature range.
