Adjustable DC-DC Booster- LM2577
Question on LM Ask Question.
Non-synchronous rectification Input voltage: This is how a basic boost regulator works. I need to boost a 3V source to 15V and this is nicely done by the product. The output switch can’t handle it. HenryLachica The seller meant exactly what they said. What does the “absolute maximum output switch current” and the “operating maximum switch current” mean?
The next question is can the LM handle more than 3A?
Non-isolated buck Module Rectification: While unlikely here, there could have been changes made, and you wouldn’t know. Finally, let’s do a sanity check with the data you provided. The maximum switch current is exactly that: Only dstasheet users can write reviews. Even if the switch was up to it, the 3V source would have to supply datasueet 20A. Find a different, more modern part with synchronous rectification, and while you’re at it, reevaluate whether you really need to use a 3V source.

The other 3W is wasted as heat. See Matt Young’s answer above. Home Questions Tags Users Unanswered. Several things to look at here You may also like. You datazheet simply remove the item from your cart. There are may boost converters available. Satasheet up using Email and Password. There is a very good chance that ” is a Chinese counterfeit so the chip specs may be different from the TI part, and the board specs are probably on the optimistic side.
