Definition of Terms

Output Current Accuracy: reflects the difference between the measured value of the output current (LED) and

programmed value of this current.

Efficiency: is expressed as a ratio between the electrical power into the LEDs and the total power consumed from the input

power supply.

Although this definition leads to a lower value than the boost converter efficiency, it more accurately reflects better system

performance, from the user’s point-of-view.
