Absolute Maximum Ratings may cause permanent damage. Absolute Maximum Ratings, sometimes referred to as no destruction limits, are normally tested with one
parameter at a time exceeding the limits of Output data or Electrical Characteristics. If exposed to stress above these limits, function and performance may degrade in an unspecified
manner.

CURRENT SHARING
Droop configured NQBS-720N
N mo
modules are available
lable for current sharing or redundancy applications. These
modules can be operated in parallel
rallel for current sh
sharing or redundancy applications by tying the respective
e together on dedicated power and ground copper planes. Sharing within 5%
inputs and outputs of each module
of full load rating can
n be expecte
expected between
etween m
modules. To optimize module performance, care should be taken
put and ou
ed
to maintain equal input
output impedance
paths for each module. If one or more modules connected to a
ed, the other mo
common load is disabled,
modules will automatically pick up the load provided that the rated power
aining m
e is not exc
of each remaining
module
exceeded.
