Fault Protection
Unlike a “Buck” or step-down regulator it is not possible
to provide a boost regulator with short-circuit protection.
As revealed in the block diagram of Figure 1-1, inhibiting
the MOSFET switching action only disables the regulator’s
boost function. Therefore under a severe output impedance
fault the control circuit cannot disconnect the output from
the input source.
To prevent an output over-current or short-circuit fault
from propagating to the input bus, a fuse or equivalent
over-current protection is recommended at the input of
the module. Whatever form of protection is selected, it is
important to note that the impedance and/or voltage drop
of the series element will add to the regulator’s minimum
input voltage requirements. Power up may also be affected.
The combination of an input surge current with an im-
pedance in series with the regulator input may cause the
input voltage to momentarily dip back below the UVLO
threshold. Ensure that the fuse rating or input current
limit threshold are designed with a generous margin.
