LT1638 Power Supply

Hello Luc123,

for a spec related questions a look in the spec is often very helpful:

In the datasheet of the LT1638 we state on page 1 following:

This should answer your question, correct?

kind regards

Markus

Thanks Markus,

I had a few of these ICs blowing up and just wanted to double check if the 44V limit was correct.

I have a voltage clipper circuit setup on the 24V supply but don't think this is working as should.

I will investigate further.

Thanks again,

Dan

Hello Luc123,

if you experience frequent failures maybe a closer look on power dissipation/output load for 24V supply might be a valid option.
