DescriptionThe UCC39002 device is an advanced, high-
performance, and low-cost load share controller that
provides all necessary functionsto parallel multiple
independent power supplies or DC-to-DC modules.
Targeted for high-reliability applications in server,
workstation, telecom, and other distributed power
systems, the controlleris suitable for N+1 redundant
systemsor high current applications
shelf power supplies mustbe paralleled.
The BiCMOS UCC39002is based
master or slave architecture of
UC3907 load share controllers. The
better than 1% current share error full load by usinga very low offset
trimmed current sense amplifier
negative feedback loop. And with
common-mode rangeof0Vto
current sense resistor, RSHUNT,
either the GND return pathorin
railof the power supply.
