I am trying to build a very simple circuit that uses a TTP223 module to control a high power LED such as a CREE XML, XPG, XRE powered by 1 single 3.7 li-ion battery. My understanding is that the output current max out at 8mA which is well below the operating amp of the LED itself. I have read about using transistors or mosfet to increase the current or voltage to achieve this but I can not figure out how to hook it up if both share the same power source. also I have looked at the CN5711 chip which is used as a constant current LED driver but I have no idea how to trigger it to get it to turn on and off with the TTP223. any help is appreciated. Thank you!.
