8. Adjusting Peak Current Limit :
As shown in Figure 12,
a combined 2.8k
internal resistance is connected to the
non-inverting lead on the PWM comparator. A external
resistance of Rx on the current limit pin forms a parallel
resistance with the 2.8k
when the internal diodes are
biased by the main current source of 900uA.
Figure 12. Peak Current Limit Adjustment
For example, FSDx0365RNB has a typical Sense FET peak
current limit (I
LIM
) of 2.15A. I
LIM
can be adjusted to 1.5A
by inserting Rx between the Ipk pin and the ground. The
value of the Rx can be estimated by the following equations:
2.15A : 1.5A = 2.8k
: Xk
,
X = Rx || 2.8k
.
(X represents the resistance of the parallel network)
