GENERAL DESCRIPTION
High performance makes it suited for replacing the simple ballast resistors that are used in general white LED solutions. It supports up to 30mA current per string. Compared with ballast resistors, the driver has many advantages such as lower dropout voltage, much lower bias variation with supply voltage variation and better efficiency The SGM3127 is available in a Green SOT-23-6 package. It operates over an ambient temperature range of -40℃ to +85℃.FEATURES
