Hello,
I would need some help determining an inductor in spec sheet:
In the diagram 'Voltage boosted boost Converter' on page 10. WHAT does the inductor refer to. A transformer? there is three legs and this is confusing me. Is this a part I can buy, if so, any part number at digikey ?
Thanks
It's drawn as a tapped inductor; but the caption makes clear that it's a transformer with interleaved windings. The end of one winding is connected to the start of the other. The secondary has 5 times as many turns as the primary and the total inductance is 4mH. That means the primary is 110nH and the secondary is 2.8mH because inductance is proportional to number of turns squared. You must buy a suitable pot core and wind this yourself.
