Magnetics for LM258X Flyback Regulator
These standard flyback regulator transformers are designed for use with National Semiconductor LM2585, LM2586, LM2587 and LM2588 SIMPLE SWITCHER(R) switching regulators. They are available in surface mount and through hole configurations. All feature 500 V isolation between windings and a variety of available turns ratios.
