Kinetic Technologies has introduced KTD2691, an ideal power driver solution for high-power flash LEDs. It includes one current source that 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 conditions.

Various protection features are integrated into KTD2691, including LED fault (open or short) protection, flash timeout protection, and thermal shutdown protection.

KTD2691 is available in a RoHS and Green 8-ball 1.519 mm x 0.808 mm x 0.500 mm WLCSP package with 0.35mm pitch.
