SOFT START TIME PROGRAMMING
INPUT CAPACITOR SELECTION
The soft start feature allows the output voltage to ramp up in
a controlled manner, eliminating output voltage overshoot
during soft start and limiting inrush current. The soft start
time is set to 3 ms.
A minimum 10 µF ceramic capacitor is required, placed near
the PVINx pin. In this application, one X5R ceramic capacitor of
10 µF and 25 V is recommended.
