(1)
The voltage rating of the input capacitor must be selected for the desired operating input voltage range of the regulator. To operate the
regulator at a higher input voltage, select a capacitor with the next higher voltage rating.
(2)
The maximum rating of the ceramic capacitor limits the regulator operating input voltage to 20 V. Select a alternative ceramic
component to operate at a higher input voltage.
(3)
A total capacitance of 2 F is an acceptable replacement value for a single 2.2-F ceramic capacitor
When configured per the standard application, the PTN78020 power module produces a regulated output voltage
following the application of a valid input source voltage. During power up, internal soft-start circuitry slows the
rate that the output voltage rises, thereby limiting the amount of in-rush current that can be drawn from the input
source. The soft-start circuitry introduces a short time delay (typically 5 ms – 10 ms) into the power-up
characteristic. This is from the point that a valid input source is recognized. Figure 26 shows the power-up
waveforms for a PTN78020W, operating from a 12-V input and with the output voltage adjusted to 5 V. The
waveforms were measured with a 1.5-A resistive load.
