Abstract

See full text

A DC-DC converter for supplying a gradually increasing voltage via a soft start circuit from a first powered domain to a second unpowered domain. The powered domain may be connected to a primary winding of a first transformer, and the unpowered domain may be connected to the secondary winding of the first transformer. The unpowered domain may respond to an applied voltage from the soft start circuit by supplying a feedback signal to the powered domain via a feedback circuit. The feedback signal indicates the power supplied from the secondary winding of the first transformer to the unpowered domain is satisfactory.
