Alternatively, high-power applications that do not
require highly accurate current-limit protection can
reduce the overall power dissipation by connecting a
series RC circuit across the inductor (Figure 4b) with an
equivalent time constant:
R
and:
where R CSHL is the required current-sense resistor and
R DCR is the inductor’s series DC resistance. Use the
typical inductance and R DCR values provided by the
inductor manufacturer.
Carefully observe the PCB layout guidelines to ensure
the noise and DC errors do not corrupt the differential
current-sense signals seen by CS and OUT. Place the
sense resistor close to the IC with short, direct traces,
making a Kelvin-sense connection to the current-sense
