Overview
WLED Driver with 1~2 Cells Input LD7291 5/31/2007 REV: 00a General Description The 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.
