One of the key features of the UCC28950 phase-shifted, full-bridge controller is its ability to synchronize its main oscillator to an external clock source. In this way, multiple controllers can be synchronized to improve performance criteria of the end power supply. This application report expands the details of the synchronization capability of the UCC28950, provides examples of simple circuits - 48-VIN, 12-VOUT Loadshare System Using the UCC39002 with Three DC-DC Modules (Rev. A)PDF, 227 Kb, Revision: A, File published: Feb 14, 2003
This application note features the UCC39002 BiCMOS 8-pin advanced load share controller and specifically illustrates equal current sharing between three 48-VDC to 12-VDC power modules, each rated for 8.4-A maximum output current, paralleled to supply a load of up to 24 A. The example uses high-side current sensing with the bias for the controllers supplied directly from the module?s output voltage - Pre-biased Output Voltage Startup Operation of the UCC28950PDF, 137 Kb, File published: Aug 1, 2011

The UC3907 family of Load Share Controller ICs provides all the necessary features to allow multiple independent power modules to be paralleled, so each module supplies only its proportionate share to total load current. Many power supply manufacturers have found it economically feasible to make standard modular power supplies which are easily paralleled for higher current applications. If speci
