The LTC
廬
4350 is a load share controller that allows
systems to equally load multiple power supplies con-
nected in parallel. The output voltage of each supply is
adjusted using the SENSE
+
input until all currents match
the share bus. The LTC4350 also isolates supply failures
by turning off the series pass transistors and identifying
the failed supply. The failed supply can then be removed
and replaced with a new unit without turning off the
system power. The LTC4350 is available in a 16-pin
narrow SSOP package.
