8.3.8 Construction

The basic construction of the DCR01 series of devices is the same as standard integrated circuits. The molded package contains no substrate. The DCR01 series of devices are constructed using an IC, low dropout linear regulator, rectifier diodes, and a wound magnetic toroid on a leadframe. Because the package contains no solder, the devices do not require any special printed-circuit board (PCB) assembly processing. This architecture results in an isolated DC/DC converter with inherently high reliability.
