Offset Programming Pin.

Internally fixed at 1.240V, connecting a ROFFSET resistor vs. SGND allows

32 OFFSET 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.
