An alternative to the OKR-T/6 - GE NSR006A0X54Z DC/DC converter

[DrMA]

Browsing around for electronics tonight I found a DC/DC converter very very similar to the ubiquitous OKR-T/6 in pretty much all specs, except the trim resistor. Turns out, the GE chip takes a trim resistor in the 1KΩ range, which introduces the potential to use digital POTs directly to set the output voltage.

I think it's just a rebranded OKR - the pot needed on this one for 3.3v - 6v is around 200 ohms.

^^This. It is identical in EVERY way except cosmetic. R_TRIM values are exactly the same.

As they are for the the TI PTR08060 and PTR08100

That GE assembly brings nothing new to the table and costs more to boot.

Yep, you guys are right. I must've misread the data sheet the first time around... Now, how do you close a thread?

For the most part - MOST ALL electronic components have 3 EXACT "replicas" in the market, built by 3 Different manufacturers. to the EXACT same specification (or better). Agreements between parties are confidential. But just know - they exist for reasons we are not aware of. This is per two tech's from two different major manufacterers - all of which are listed above.

LOL that makes 4.....the one I saw has a higher max Vout but also wants a higher input...nice thing to know tho thx for the tidbit SM
