Sense resistor values of 50m
for the 5V output voltage versions. When choosing an
inductance different from 47H the Sense resistor has to be changed also.
To achieve the same effect of slope compensation in the adjustable voltage version also
the inductance in H is given by
The inductance value determines together with the input voltage, the output voltage and
the switching frequency the current ripple which occurs during normal operation of the
step down converter. This current ripple is important for the all over ripple at the output
of the switching converter. .
When picking finally the inductance of a certain supplier (Epcos, Coilcraft etc.) the
saturation current has to be considered. The saturation current value of the desired
inductance has to be higher than the maximum load current which can appear in the
actual application.
7.10.2
Determining the current limit
The peak current which the buck converter is able to provide is determined by the peak
current limit threshold voltage VLIM and the sense resistor RSENSE. With a maximum peak
