圣邦微原装供应500毫安降压/增压充油泵LED驱动器-SGM3140

       The SGM3140 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 SGM3140 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 components. 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.
