8. Adjusting Peak Current Limit : As shown in Figure 13,
a combined 2.8kΩ 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 2.8kΩ when the internal diodes are
biased by the main current source of 900uA.
For example, FSDx0365RN has a typical Sense FET peak
current limit (I
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 = 2.8kΩ : XkΩ ,
X = Rx || 2.8kΩ .
(X represents the resistance of the parallel network)
