Application information
21/30
Figure 15.
Short-circuit current VIN = 30 V
In Figure 14 and Figure 15, for example, it can be observed that when the input voltage
increases for a given component list, the current peak increases also. The current limit is
immediately triggered but the current peak increases until the current ripple during TOFF is
equal to the current ripple during TON.

Application circuit
Figure 16 shows the evaluation board application circuit, where the input supply voltage,
VCC, can range from 4.4 V to 25 V due to the voltage rating of the input capacitor, and the
output voltage is adjustable from 1.235 V to VCC.
