When regulating an output of 0.606V, short FB to OUT and keep R6 connected from FB to GND. If a different output voltage is desired, revisit the feedback resistor-divider (R5), the inductor, and output-capacitor calculations (refer to the Inductor Selection and OutputCapacitor Selection sections in the MAX15066 IC data sheet).
