2.9 Start-Up
The start-up voltage waveform of the TPS54614 EVM is shown in
Figure 2–15. The TPS54614 output begins to rise when the input rises above
the 3.0-V startup level. The output voltage then ramps linearly to 1.8 V in 3.6
ms. The start-up time is independent of input voltage and load. The slow start
time can be made slower by using an external slow start capacitor (C6).
