ADM1041ARQ-REEL7

GENERAL
The ADM1041 is a secondary-side and management IC specifically designed to minimize external component counts and to eliminate the need for manual calibration or adjustment on the secondary-side controller.
The principle application of this IC is to provide voltage control, current share, and housekeeping functions for single output in N+1 server power supplies.PRODUCT
