Figure 11. Power-Up Application Circuit
When the Track pin is connected to the input voltage the Auto-Track function is permanently disengaged. This
allows the module to power up entirely under the control of its internal soft-start circuitry. When power up is
under soft-start control, the output voltage rises to the set-point at a quicker and more linear rate.
From the moment a valid input voltage is applied, the soft-start control introduces a short time delay (typically
5 ms–10 ms) before allowing the output voltage to rise.
Figure 12. Power-Up Waveforms
The output then progressively rises to the module’s setpoint voltage. Figure 12 shows the soft-start power-up
characteristic of the 22-A output product (PTH05020W), operating from a 5-V input bus and configured for a
3.3-V output. The waveforms were measured with a 5-A resistive load and the Auto-Track feature disabled. The
initial rise in input current when the input voltage first starts to rise is the charge current drawn by the input
capacitors. Power-up is complete within 15 ms.
For protection against load faults, all modules incorporate output overcurrent protection. Applying a load that
exceeds the regulator’s overcurrent threshold causes the regulated output to shut down. Following shutdown, a
module periodically attempts to recover by initiating a soft-start powerup. This is described as a hiccup mode of
operation, whereby the module continues in a cycle of successive shutdown and power up until the load fault is
removed. During this period, the average current flowing into the fault is significantly reduced. Once the fault is
removed, the module automatically recovers and returns to normal operation.
