0.075 Ohm RSense

FB Voltage = 0.01 x VSense * RSet
0.6 = 0.01 * (RSense * Current) * RSet
0.6 = 0.01 * 0.075 * Current * RSet
0.6 = 0.00075 * Current * RSet
800 = Current * RSet

RSet = 800 / Current

0.15 Ohm RSense

FB Voltage = 0.01 x VSense * RSet
0.6 = 0.01 * (RSense * Current) * RSet
0.6 = 0.01 * 0.15 * Current * RSet
0.6 = 0.0015 * Current * RSet
400 = Current * RSet

RSet = 400 / Current
