The SM8131B is a charge pump DC/DC converter that switches between ×1and ×1.5 automatically. The SM8131B switches between ×1 and ×1.5 according to detected LED drive current, so that the battery life can be prolonged to the fullest extent. Since the connected LED are all detected for the switching, ■ Battery life extension by automatic charge pump switch between ×1 and ×1.5 according to the\ndetection of the LED drive current\n■ Controlling 1 to 6 lights of white LED connected in parallel\n■ Set up LED drive current value by external resistor (5kΩ:5mA/ch, 15kΩ:15mA/ch, 20kΩ:20mA/ch)\n■ Dividin;
