Constant Current LED Driver Power Supply Current Adjustable by Internal Pot, 700mA 50V-100V 70W

today i'm gonna show you how to make constant current led driver by using a single ic the interesting thing about this ic that it can work in with low voltage and high voltage without any problem this is the data sheet of the ic unfortunately i can't find english datasheet for this ic you can translate it but i think it is obvious even without translation it can drive the led with current range from 5 milliamp to 110 milliamp it has a mosfet inside that can handle 600 volt there are three different package for this ic i have this one which is s08 package this ic has eight pins but you have to use in three of them only pin number one number two and seven this is the circuit it is very simple you just need a bridge diode ic resistor and some leads if your supply voltage was dc voltage so you don't need the bridge diode anymore by using this resistor you can set the current that's passing
