LMZ31506 Parallel Operation
PDF, 315 Kb, File published: Jul 2, 2013
The LMZ31506 is a 2.95-V to 14.5-V input, 6-A output, integrated power solution which integrates the PWM controller, power MOSFETs, inductor and passives in a low-profile, QFN package. For applications requiring greater than 6 A, it is possible to parallel two or more LMZ31506 devices by following the recommendations in this paper.
