Brief Description
KTD2684 is the ideal power solution for high-power flash
LEDs. It includes a highly integrated synchronous boost
converter and two current sources, providing a very small
total solution in portable application. It has both I2C
interface and hardware STROBE/TORCH pins for
maximum control flexibility. The two integrated current
sources are independently controlled, their on/off
conditions and current settings in Flash/Torch/IR modes
can be programmed independently by the I2C interface. It
also has three selectable input low voltage protection
modes to prevent a system reset under low battery
condition. Thermal regulation is also integrated to limit the
IC temperature and continuously provide the maximum
output current.
Various protection features are integrated into KTD2684,
including cycle-by-cycle input current limit protection,
output over-voltage protection, LED fault (open or short)
protection, flash timeout protection and thermal shutdown
protection.
KTD2684 is available in a RoHS and Green 12-ball
1.42mm x 1.66mm WLCSP package with 0.4mm pitch.
