What you’re wanting is physically not possible. Sign up using Facebook. I only get 0. With the solar panel, it’s actually possible to have that kind of supply.

I need to boost a 3V source to 15V and this is nicely done by the product. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

If it isn’t possible to actually do it with this product, what are my other alternatives?

The other 3W is wasted as heat. Enter your destination to get a shipping estimate.

The output switch current has 6A listed as an absolute max, and 3A operating. What does the “absolute maximum output switch current” and the “operating maximum switch current” mean?

We will use solar panels so that would do it. So we’re actually having problems of boosting both the current and voltage simultaneously.

LM2577-12.0 Boost Converter Overview

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. It’s a good habit to get into. The LM series of regulators are monolithic integrated circuits that provide all the active functions for a step-up buck switching regulator, capable of driving a 3A load withexcellent line and load regulation.

The maximum switch current is exactly that: Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

Post as a guest Name. To see why, let’s take a look at the datasheet again.

Adjustable DC-DC Booster- LM

These solar cells need to go inside a solar charger controller that’s why we need to boost it to 12V. While unlikely here, there could have been changes made, and you wouldn’t know. This is how a basic boost lm2577d works. The problem is the current out would not be enough when we use om2577s boost converter. But the current isn’t the same because I need about 2.

I’m trying to work around it. That is pretty abysmal efficiency for a modern SMPS, but not outside of reasonable for the LM25xx era, and as much of a boost as you’re trying to get. Even if the switch was up to it, the 3V source would have to supply over 20A.
