Obsolete Power Supply IC #17

Open bdring opened 4 years ago

bdring commented 4 years ago

The MP1584EN power supply IC obsolete. I have been using it for years and did not notice it until recently. My PCB supplier has no trouble getting them though.

I have a test controller on order with the Diodes Inc AP64350SP-13. It is very close in capability and has a higher max input voltage. I will switch to that if it works out.

Thats the one iam using. Works fine without problems. Getting 5v output with 115k and 22.1k resistor on feedback line.

For the external driver version, the TPS54360 (C44377) is specified, however it seems to have been replaced by the TPS54360B version (C524806). Is this just a drop in replacement or will I need to change some other components?

Let me Google that for you

I found this.

Looks like it is just a polymer coating. It should be a drop in replacement.
