Set Current Calculation
IOUT
= (reference voltage × set current ratio)/(sense resistor (SEN) value)
Since the reference voltage can be set to either 0.2, 0.134, 0.1, or 0.066 V with the serial data, the output current can
be set with either the reference voltage or the value of the sense resistor SEN.
