10. Current Limit Setting
When the output of the current sense amplifier (COx in the
block diagram) exceeds the voltage on the I
LIM
pin, the part
will latch off. For inductive sensing, the I
LIM
pin voltage
should be set based on the inductor’s maximum resistance
(R
LMAX
). The design must consider the inductor’s
resistance increase due to current heating and ambient
temperature rise. Also, depending on the current sense
points, the circuit board may add additional resistance. In
general, the temperature coefficient of copper is +0.39% per
C. To set the level of the I
LIM
pin:
VILIM
(IOUT,LIM
ILo2)
R
GILIM
(31)
where:
I
OUT,LIM
is the current limit threshold of the converter;
Δ
I
Lo
/2 is half the inductor ripple current;
R is R
LMAX
+ R
PCB;
G
ILIM
is the current sense to I
LIM
gain.
For the overcurrent protection to work properly, the
current sense time constant (RC) should be slightly larger
than the R
L
time constant. If the RC time constant is too fast,
a step load change will cause the sensed current waveform
to appear larger than the actual inductor current and will trip
the current limit at a lower level than expected.
