Output Voltage
Load Regulation
Line Regulation
UV Lockout
Current Limit Voltage
Oscillator Frequency
Oscillator Max Duty Cycle
DH Sink/Source Current
Output Voltage Tempco
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 16935F 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. xxxxx refers to any valid VID code.
