Feature Description (continued)

Figure 8. RESET Timing Behavior

8.3.2 Enable and Start-Up

Start-up and shutdown of the LM53603 are controlled by the EN input. Applying a voltage of

≥ 2 V activates the

device, while a voltage of

≤ 0.8 V is required to shut it down. The EN input may also be connected directly to the

input voltage supply, if this feature is not needed. This input must not be left floating. The LM53603 uses a

reference based soft-start, that prevents output voltage overshoots and large inrush currents as the regulator is

starting up. A typical start-up waveform is shown in Figure 9 along with typical timings.
