Additional preview pages of the SGM3140B datasheet.

The SGM3140B is a current-regulated charge pump ideal for powering high brightness LEDs for camera flash applications.

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 Green TDFN-3×3-10L package and is specified over an ambient temperature range of -40℃ to +85℃.
