MB3873 Overview
The MB3873 is a pulse frequency modulation (PFM) type multi-resonance AC/DC converter IC providing soft switching functions in a more pact, higher-efficiency, low-noise package. Since this product allows reduced number of the ponents and reduced size of the transformer, it is also patible with the miniaturization of AC adaptor. The product retains the multi-resonance for the non-load, over-load and load...
