Hot Swappable

Load Share Controller

The LTC

systems to equally load multiple power supplies con-

nected in parallel. The output voltage of each supply is

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.
