Abstract
A package for a power magnetic device containing an isolation transformer having a primary and secondary winding, and a method of manufacture therefor. The package includes: an encapsulant substantially surrounding the isolation transformer, first and second cavities formed in the encapsulant proximate the primary winding and the secondary winding, the first cavity exposing a first tap of the primary winding and adapted to receive a switch therein, the first tap of the primary winding adapted to couple the switch to the primary winding, the second cavity exposing a first tap of the secondary winding and adapted to receive a first rectifying device therein, the first tap of the secondary winding adapted to couple the first rectifying device to the secondary winding, the first and second cavities adapted to be encapsulated after receiving the switch and the first rectifying device therein to allow the switch, the first rectifying device and the primary and secondary windings of the isolation transformer to be joined into a unitarily encapsulated package.
