Feature Description (continued)

Figure 5. High Voltage Application

The following is a practical step-by-step design procedure on how to use the UCC39002 to parallel power

modules for load sharing.

7.3.10 Paralleling the Power Modules

•

•

•

•

N = number of modules

NOTE

The power modules to be paralleled must be equipped with true remote sense or access

to the feedback divider of the module’s error amplifier.

A typical high side application for a single module is shown in Figure 6 and is repeated for each module to be

paralleled.
