Isolated µModule Power Products Simple, Compact, Isolated µModule DC/DC Converters Linear Technology’s isolated µModule® power products provide simple and compact isolated power supply solutions. These products include isolated transformer, control circuitry, power switch and other supporting components in a small, low profile BGA package. Only a few resistors, input and output capacitors are required to complete the design.
