Applications Information (Continued)
INCREASING THE CURRENT LIMIT THRESHOLD
The current limit threshold is nominally 1.25A, with a mini-
mum guaranteed value of 1.0A. If, at maximum load current,
the lower peak of the inductor current (I
PK- in Figure 13)
exceeds 1.0A, resistor R
CL must be added between SGND
and I
SEN to increase the current limit threshold to equal or
exceed that lower peak current. This resistor diverts some of
the recirculating current from the internal sense resistor so
that a higher current level is needed to switch the internal
current limit comparator. I
PK- is calculated from:
(11)
where I
O(max) is the maximum load current, and IOR(min) is
the minimum ripple current calculated using Equation 10.
R
CL is calculated from:
