How to connect 4 pin Inductor

[sudil99]

I want to make dc dc converter. So I bought **broken link removed** as recommended in datasheet. But this inductor has 4 pins while I just need 2 pins; one to Vin and one to SW.

how/which pins, do I connect the pins to Vin and SW?

Unfortunately, you're the only one who (hopefully) knows what this inductor is. There's no valid link.

It's essential to know the inductor type. A popular fault is to "abuse" a current compensated choke as a storage inductor, which never works.

Sorry for the link. I corrected it. Now, its working. Its CR43NP-4R7, 4.7uH inductor. This is the one of the recommended inductors in the datasheet of the LTC3429, for this application. I am just confused about the pins, because it has 4 pins, and I need only two pins.

The inductor seems O.K., but the pin assignment isn't given in the datasheet. Most likely two pins are unconnected and only used for mechanical purposes.

You need to ask Sumida or wait until you get the part.
