These solar cells need to go inside a solar charger controller that’s why we need to boost it to 12V.

Even if the switch was up to it, the 3V source would have to supply over 20A. TI released a revised version in April Datzsheet Required, but never shown. First, always get your datasheet straight from the manufacturer. Digikey might be a good place to start. The switch switches the input current to ground through the inductor and sense resistor.

We would be able to supply 0. The version you linked to is dated See Matt Young’s answer above. This is how a basic boost regulator works. Because it is a boost converter and you can’t break physics.

LM DC-DC Adjustable PSU Module

If you want 15V 2. Question on LM Ask Question. Distributor Cooperated Designers Sponsorship. This module uses the adjustable output version, it would facilitate your application and be your good assistant in your debugging. I have a hard time fully understanding the datasheet of LM I only get 0. 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.

Power is conserved, and you lose a datasheef or more than a bit of power to the regulator i. I can’t see any specifications on the datasheet that refers to the maximum input.

LM2577-12.0 Boost Converter Overview

To see why, let’s take a look at the datasheet again. Henry Lachica 8 6. Home Questions Tags Users Unanswered.

If it isn’t possible to actually do it with this product, what are my other alternatives? Sign up lm2577w Email and Password. 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.

Adjustable DC-DC Booster- LM2577

The problem is the current out would not be enough when we use a boost converter. HenryLachica The seller meant exactly what they said.

There isn’t a datasueet in the world that will make that possible. Post as a guest Name. So we’re actually having problems of boosting both the current and voltage dataseet. Non-synchronous rectification Input voltage: When I tried testing it, it seems that it l2577s handle more current than 3A and i’m just too scared to test it out as I might break the product.

The other 3W is wasted as heat. This is your maximum input current. It’s just making life harder.
