Figure 25 shows an example of a compensation network stabilizing the system with ceramic
capacitors at the output (the optimum component value depends on the application).

8.10 External SOFT_START network
At startup the device can quickly increase the current up to the current limit in order to
charge the output capacitor. If soft ramp-up of the output voltage is required, an external
soft-start network can be implemented as shown in Figure 26. The capacitor C
SS
is charged
up to an external reference through the R
SS
and the BJT clamps the COMP pin.
This clamps the duty cycle, limiting the slew rate of the output voltage.
