TI released a revised version in April You have no obligation to purchase the product once you know the price. If it isn’t possible to actually do it with this product, what are my other alternatives?

I’m trying to work around it. I tried scanning through the datasheet and I fail to see its maximum input current.

This module uses the adjustable output version, it would facilitate your application and be your good assistant in your debugging. Digikey might be a good place to start. Okay, that I understand. Power is conserved, and you lose a bit or more than a bit of power to datasheeg regulator i. Sign up or log in Sign up using Google.

See Matt Young’s answer above.

I’m actually looking into another product but I’m not sure if it’ll work again if the same inputs were used. Sign up using Facebook. The version you linked to is dated The next question is can the LM handle more than 3A? Even if the switch was up to it, the 3V source would have to supply over 20A. This is how a basic boost regulator works. The problem is the current out would not be enough when we use a boost converter.

Please, lm25777s in or register. When I tried testing it, it seems that it can handle more current than 3A and i’m just too scared to test it out as I might break the product. Henry Lachica 8 6. 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. I can’t see any specifications on the datasheet that refers to the maximum input.

Post as a guest Name. If ratasheet trying to get 15V dqtasheet 3A, this part is not going to do it. Non-synchronous rectification Input voltage: I need to boost a 3V source to 15V and this is nicely done by the product. Enter your destination to get a shipping estimate. This is your maximum input current. The source is actually a solar panel. HenryLachica The seller meant exactly what they said. The supply of our tested solar panel had a voltage of V and a current of 6A.


If you want 15V 2.

Adjustable DC-DC Booster- LM2577

The output switch current has 6A listed as an absolute max, and 3A operating. The maximum switch current is exactly that: 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.

I’ve seen and looked into it.

LM2577 DC-DC Step Up Adjustable PSU Module

Non-isolated buck Module Rectification: But the current isn’t the same because I need about 2. If you read the datasheet of the LM, it has an absolute maximum output switch current of 6. There isn’t a product in the world that will make that possible.

Put another way, you’re putting 9W into the regulator, and getting 6W of useful power out. I only get 0. Distributor Cooperated Designers Sponsorship.

Finally, let’s do a sanity check with the data you provided.
