Inductorless, Single Flash LED Driver with Programmable 1.5A Current Source

KTD2691 is the ideal power solution for high-power flash LEDs. It includes one current source which can drive up to 1.5 A of LED flash current or up to 376 mA of torch current, and provides a very small total solution in portable applications. The device has both an I2C interface and a hardware STROBE pin for maximum control flexibility. The integrated current source on/off and current settings in Flash/Torch/IR modes can be programmed by the I2C interface. A selectable input low voltage protection function can prevent a system reset under low battery condition.
