Description:
   HM5182 is a three-function flashlight LED driver chip. It uses a very small SOT23 lead-free package and only requires one capacitor device, which saves PCB space and system cost. Three dry batteries or one lithium battery can drive 1-5W LED. HM5182 changes the output mode by disconnecting and connecting the switch, which can realize brightness adjustment and flash function.
