HenryLachica The seller meant exactly what darasheet said. To see why, let’s take a look at the datasheet again. Non-synchronous rectification Input voltage: I only get 0.

Non-isolated buck Module Rectification: The problem is the current out would not be enough when we use a boost converter.

Find a different, more modern part with synchronous rectification, and while adtasheet at it, reevaluate whether you really need to use a 3V source.

The maximum switch current is exactly that: If it isn’t possible to actually do it with this product, what are my other alternatives? Even if the switch was up to it, the 3V source would have to supply datasheet 20A.

LMADJ (~40VDC to 65V 3A Step Up Voltage Regulator)

The other 3W is wasted as heat. So if we stack it up, we’re gonna have a total of 4V and 6A, as a source tested the solar cells during a very hot day. This module uses the adjustable output version, it would facilitate your application and be your good assistant in your debugging.

See Matt Young’s answer above. I tried scanning through the datasheet and I fail to see its maximum input current.

Please, log in or register. It’s just making life harder.

Adjustable DC-DC Booster- LM

Our price is lower than the manufacturer’s “minimum advertised price. You may also like. What does the “absolute maximum output switch current” and the “operating maximum switch current” mean? Sign up dattasheet Email and Password. Only registered users can write reviews.

Because it is a boost converter and you can’t break physics. I can’t see any specifications on the datasheet that refers to the maximum input. Email Required, but never shown. I’m trying to work around it.


It’s not going to work. Lm2577 would be able to supply 0. There are may boost converters available. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I bought this product that has a LM in it and the specifications indicated by the seller that it can have a maximum output dataaheet of 2A with a maximum input current of 3A. I’m actually looking into another product but I’m not sure if it’ll work again if the same inputs were used.

LM2577-12.0 Boost Converter Overview

If you want 15V 2. TI released a revised version in April Granted, it’s a bit difficult to calculate exact switch current from a desired output current, but the point is, at a max switch current of 3A, it’s definitely not going to give you 13A switch current is always higher than output current. 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.
