Title: Chargepump question
Post by: DutchMF on December 03, 2012, 04:50:11 PM
In a lot of the build docs the difference between 'SCPA' and 'CPA' designations for the TC1044 is stressed, so I decided to add 10 of the 'SCPA' types to my next Mouser order...... Guess what: Sold out, no new ones 'till the beginning of next year! Now, I saw that they do have the 'SEPA' type, and if interpreted the datasheet correctly, the only difference with the 'SCPA' is the temperature range they can handle... Am I right?

You are correct, sir. The "S" is for ... um ... doesn't suck.

Are they out of the MAX, LT1054, and 7660, too? :/

Didn't check the MAX, so I will tomorrow, but LT1054 (expensive!) and 7660 are still in stock.... Mind you, I could get all those from Banzai for instance, but the prices they ask are ridiculous! Other prices there are not so bad, but those chargepumps....

I need to pick up some of these... what is the preferred model? LT, MAX, TC... which one is best?
