Turn-On: With a valid input source voltage applied, the converter produces a regulated output voltage within
10 ms of the output being enabled. Figure 6 shows the output response of the PTEA following the removal of the
logic-low signal from the Remote On/Off (pin 2); see Figure 5. This corresponds to the rise in V_EN in Figure 6.
Although the rise-time of the output voltage is short (<5 ms), the indicated delay time will vary depending upon
the input voltage and the module’s internal timing. The waveforms were measured with 48 VDC input voltage,
and a 15-A resistive load.
