Texas Instruments LM36011 Inductorless LED Flash Drivers offer a high level of adjustability and a small-solution size of 4mm2. The device produces up to 1.5A of LED flash current or up to 376mA of torch current. The accurately programmable current source retains this current without the need of a pre-regulated voltage, saving both solution size and cost. An I2C-compatible interface controls features including 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 LM36011 operates over an –40°C to +85°C ambient temperature range.
