Introduction

AI Translation

The SGM3141 is a current-regulated buck-boost charge pump LED driver capable of delivering 700mA output current. It is ideally suited for powering high-brightness LEDs in camera flash applications. The SGM3141 features 1×/2× operating modes to control output current in flash and torch modes. With a supply voltage range of 2.7V to 5.5V, it is well suited for applications powered by a single Li-ion cell or 3 to 4 NiCd, NiMH, or alkaline cells. The SGM3141 automatically transitions between boost and buck modes, ensuring LED current is not limited by forward voltage. The high switching frequency allows the use of small passive components. The low feedback reference voltage enables the use of compact 0603 current-sense resistors. The SGM3141 offers ultralow shutdown current and soft-start functionality. The built-in soft-start circuit prevents excessive inrush current during startup. The SGM3141 also incorporates comprehensive protection features, including overvoltage protection, overcurrent protection, and thermal shutdown. The SGM3141 is available in a Green TDFN-3×3-10L package and operates over an ambient temperature range of -40°C to +85°C.
