Definition of Terms
Output Current Accuracy: reflects the difference between the measured value of the output current (LED) and
programmed value of this current.
Current Matching: refers to the absolute value of difference in current between the two LED branches.
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 per-
formance, from the user’s point-of-view.
Typical Application
voltage. The output current can then be programmed to any
desired
FAN5608DMPX/FAN5608MPX version uses a single exter-
nal resistor to set the current, and to turn the device ON and
OFF. The FAN5608DMPX/FAN5608MPX is available in an
