This is how a basic boost regulator works. The schematic is simple, easy to build and cost effective, producing 12V from a 5V unregulated supply with a maximum output current of mA.

This module uses the adjustable datasbeet version, it would facilitate your application and be your good assistant in your debugging. We will use solar panels so that would do it. Question on LM Ask Question. Non-synchronous rectification Input voltage: First, always get your datasheet straight from the manufacturer.

Sign up using Email and Password. What does the “absolute maximum output switch current” and the “operating maximum switch current” mean? JavaScript seems to be disabled in your browser. 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. Henry Lachica 8 6. The UC – a pin to pin compatible replacement available from Texas Instruments can also be used. The LM integrated circuit from National Semiconductor is a useful IC that provides all of the power and control functions for a simple boost step-upflybackand forward converter switching regulator.

Our price is lower than the manufacturer’s “minimum advertised price. This is your maximum input current. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

With the solar panel, it’s actually possible to have that kind of supply. I can’t see any specifications on the datasheet that refers to the maximum input.

Adjustable DC-DC Booster- LM2577

Okay, that I understand. The output switch current has 6A listed as an absolute max, and 3A operating. Sign up using Facebook.

Low values of ESR can be achieved by using larger value capacitors or by paralleling multiple smaller-value capacitors. You have no obligation to purchase the product once you know the price. Even if the switch was up to it, the 3V source would have to supply over 20A.

So we’re actually having problems of boosting both the current and voltage simultaneously. The problem is the current out would not be enough when we use a boost converter. I have a hard time fully understanding the datasheet of LM See Matt Young’s answer above.

TI released a revised version in April Home Questions Tags Users Unanswered. The part from Pulse has the following specifications: The input capacitor C1 should be a good quality, low ESR, 0. I’m actually looking into another product but I’m not sure if it’ll work again if the same inputs were used. If the IC is located far datadheet the supply source filter capacitors, an additional larger electrolytic capacitor e.

I tried scanning through the datasheeh and I fail to see its maximum input current. You can simply remove the item from your cart. 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. The LM is available in different packages:
