SGM3140B 500mA Buck/Boost Charge Pump LED Driver

The SGM3140B 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 SGM3140B automatically switches modes between step-up and step-down ensuring that LED curren.

SGM3140B Features

* a very low shutdown current, an automatic soft-start mode to limit inrush current, as well as over-current, over-voltage and over-temperature thermal shutdown control. A low current-sense reference voltage (47mV) allows the use of small 0603 current sensing resistors. The SGM3140B is available in Gr
