Ferrite transformer turns calculation with example : High value of flux density will saturate the core and low value of flux density will lead to core under utilization. For example we will take 1500G for dc to dc converter example. f is switching frequency converter. In our example switching frequency of dc to dc converter is 50 KHz. Ac is effective cross sectional area of ferrite core.
