SGM3141 Overview
Key Features
- The SGM3141 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 SGM3141 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
- A low current-sense reference voltage (47mV) allows the use of small 0603 current sensing resistors
- The SGM3141 is available in Green TDFN-3×3-10L package and is specified over an ambient temperature range of -40℃ to +85℃
