I an looking for 50V 90 ma IC for led light with constant current and constant voltage control
I assume the 50 V refers to the output voltage (50 V LED), but it would be good to know the input voltage to give you a more complete answer, and as power dissipation is always a concern when designing with constant current. Based on your brief requirements, you could use a NSI45090JDT4G, Constant Current Regulator for this design. The NSI45090JDT4G is a 45 V, 90 mA adjustable device.
