6W Constant Current Source LED Driver (90~265V)

The simplest form of current source is a resistor, but active current sources using transistors are able to provide a much more constant current, or controlled current . Transistor active constant current source, with details of the circuit, operation and how it can be designed. Learn about a straightforward version of a circuit that is essential in the design of analog integrated circuits. Constant-current sources figure prominently in circuit-analysis exercises and network theorems, then they seem to more or less disappear . . unless you're an IC . In this video, I describe a constant current source used to drive the LED backlights of a LCD. In this post we try to analyze what is constant current source and how it affects a load, or how it may be used with a load correctly for achieving the most…
