Procedure for Calculating the Set Current

IOUT = (reference voltage u set current ratio)/(sense resistor (SEN) value)

Since the reference voltage is 0.2 V, the following output current flows when the set current ratio is 100% and the

sense resistor is 1 :.

IOUT 0.2 V u 100/1 :

200 mA

Vary the value of the sense resistor (SEN) to vary the output current.
