Magnetics for LM258x Flyback Regulator
These standard flyback regulator transformers are designed
for use with Texas Instruments LM2585, LM2586, LM2587
and LM2588 SIMPLE SWITCHER® 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.
