WLED Driver With 1~2 Cells InputThe LD7291 is a high efficiency WLED driver to drive
maximum 3 WLEDs from single or 2 battery cells. By using
the proprietary topology, the LD7291 CAN operate under as
low as 0.85V to fully utilize the energy of battery.
The LD7291 only needs 4 external passive components to
provide the solution for driving maximum 3 WLEDs in a very
small PCB size. Furthermore, the 3 WLEDs CAN achieve
very good current matching without any extra current
/brightness control circuit. All the above functions are
integrated in a tiny SOT-26 package. The LD7291 is the
ideal solution for battery-powered LED driving applications. By Leadtrend Technology
