OFFSET
Offset Programming Pin.
Internally fixed at 1.240V, connecting a ROFFSET resistor vs. SGND allows
setting a current that is mirrored into FB pin in order to program a positive offset
according to the selected RFB. Short to SGND to disable the function.
See “Offset (Optional)” Section for details.
