WD3124DB Datasheet | Will Semiconductor

1000mA Buck/Boost Charge Pump Flash LED Driver Http//:.sh-willsemi. Description The WD3124DB is a current-regulated charge pump ideal for powering high brightness LEDs for camera flash applications. The charge pump can be set to regulate two current levels for FLASH and TORCH modes. The WD3124DB automatically switches modes between step-up and step-down ensuring that LED current does not depend on the forward voltage. It switches at 2.2MHz, allowing the use of tiny ponents. The supply voltage ranges from 2.7V to 5.5V and is ideally suited for all applications powered by a single LI-Ion battery cell or three to four NiCd, NiMH, or Alkaline battery cells. The...
