? Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device. These
are stress ratings only and functional operation of the device
at these or any other conditions above those indicated in the
operation sections of the specifications is not implied.
Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability.

V R is the nominal factory-programmed output voltage setting.
VLX LIM is the voltage on the LX pin (with internal switch ON) that will cause the oscillator to run at twice nominal
frequency in to limit the switch current through the internal N-channel switching transistor.
Measured with D 1 = MA735 (reverse current < 1 μA at a reverse voltage of 10V).
With TC115 operating in PWM mode.
See Section 4.4, “Behavior When V IN is Greater Than the Factory-Programmed V OUT Setting”.
