Contextual Info: U-129 APPLICATION NOTE UC3907 LOAD SHARE IC SIMPLIFIES PARALLEL POWER SUPPLY DESIGN MARK JORDAN SENIOR DESIGN ENGINEER INTRODUCTION Many power supply manufacturers have found it economically feasible to make standard modular power supplies which are easily paralleled for higher current applications. If special provisions are not made to equally distribute the load current among the paralleled supplies, then one or more units will hog the load current leaving the other units essentially idle.
