5 Analog Applications JournalLoad- sharing techniques: Paralleling powermodules with overcurrent protectionParalleling low-current, low-voltage power modules forhigh-current, low-voltage applications has many them are: redundancy for enhanced reliability, hot-swap capability, distributed heat removal, and design flexi-bility. Paralleling power stages requires load sharing inorder to equalize the stresses among the modules . Onemethod of load sharing , based upon the automatic master/slave architecture, is to use a dedicated controller, such asthe UCC39002, to provide for equal current distribution ofthe load current among the parallel-connected power sup-plies. The power modules must be equipped with trueremote-sense capability or an output-adjustment output current of each module is measured and com-pared to a common load -share bus. The positive sensevoltage or the voltage of the output voltage adjust pin ofeach module is adjusted to provide equal current modules are paralleled so that the entire assem-bly can support a full load much greater than an individualmodule would be capable of supplying.
