Application Information

the narrow pulses and ramp up in a controlled manner. This
is a very useful feature in some switcher topologies that re-
quire large startup currents (such as the inverting configura-
tion) which can load down the input power supply.
Note:
The lower curve shown in Figure 13 shows the Soft-start region from
0% to 100%. This is not the duty cycle percentage, but the output volt-
age percentage. Also, the Soft-start voltage range has a negative tem-
perature coefficient associated with it. See the Soft-start curve in the
electrical characteristics section.
4. Normal operation.
Above 2.8V, the circuit operates as a
standard Pulse Width Modulated switching regulator. The
capacitor will continue to charge up until it reaches the inter-
nal clamp voltage of approximately 7V. If this pin is driven
from a voltage source, the current must be limited to about
1 mA.
