13 Power-Up Characteristics

When configured as shown in the front page schematic, the TPS84210 produces a regulated output voltage following the application of a valid input voltage. During the 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 from the point that a valid input voltage is recognized. Figure 21 shows the start-up waveforms for a TPS84210, operating from a 5-V input and with the output voltage adjusted to 1.8 V. The waveform is measured with a 2-A constant current load.
