Brief Description
KTD2683B is the ideal power solution for high-power flash
LEDs. It includes a highly integrated synchronous boost
converter, two current sources and one current sink,
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 and one current sink 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 KTD2683B,
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.
KTD2683B is available in a RoHS and Green 12-ball
1.42mm x 1.66mm WLCSP package with 0.4mm pitch.
