NOTES:
(1) Low output currents, below the continuous conduction threshold will cause an increase in output voltage
beyond the load regulation limit. For Application circuit 16935E see the regulation curve on sheet 5.
(2) All VID codes not specifically listed here are invalid and cause shutdown exactly as if the shutdown pin had
been asserted. xxxx refers to any valid VID code.
