Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only. Functional operation of the device is not implied at these or any other
conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute
maximum ratings for extended periods can adversely affect device reliability.

Static Voltage Regulation
The output voltage measured at the converter output pins on the system board will be within the range
shown in Table 3, except during turn-on and turn-off periods. The static limits apply to ambient temperatures
between 0 °C and 70 °C. Static voltage regulation includes:
• DC output initial voltage and set point adjust
• Output load ranges specified in tables above
• Temperature and warm-up input voltage tolerances specified in input voltage and current
Turn-on Response Time
The output voltage will be within the specified range within 10 ms of the input voltage reaching 90% of its
nominal value with O
be inside its specified range within 10 ms. Figure 1 and Figure 2 represent typical start-up waveforms with
the maximum load current and load capacitor on the output indicated in Table 3. A pull-up resi stor of 10 kΩ
