Safety Considerations
Module’s printed circuit board meets the standards of UL flammability specifications per UL94V-0.
Feature Descriptions
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
UTEN present. When O UTEN is applied with input voltage present, the output voltage will
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 resistor of 10 k
Ω
is used between Module OK pin and 5V.
