A light emitting diode is provided, which includes an n-type contact layer and a light generating structure adjacent to the n-type contact layer. Upon installation of the adapter in the machine, the adapter enables data communication between the machine and a customer replaceable unit monitor having a second interface format that is different than the first interface format. In the best use of the invention the resonant inductor is replaced by use of the inherent leakage inductance of the transformer and for the first time eliminate the switching losses always associated with the transformer leakage inductance of all other switching converters.
