To see why, let’s take a look at the datasheet again. Enter your destination to get a shipping estimate.

So what did the seller mean by Input Current: But the current isn’t the same because I need about 2. There are may boost lm2577 datasheet available.

I lm2577 datasheet get 0. It’s not going to work. I’m trying to work around it. 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 lm2577 datasheet to give you 13A switch current is always higher than output current.

Adjustable DC-DC Booster- LM2577

The chip includes a 3A NPN switch transistor with its associated protection circuitry, consisting of current lm2577 datasheet thermal limiting, and undervoltage lockout. With the solar panel, it’s actually possible to have that kind of supply.

The input capacitor C1 should be a good lm2577 datasheet, low ESR, 0. Henry Lachica 8 6. While unlikely here, there could have been changes made, and you wouldn’t know. The supply of our tested solar panel had a voltage of V and a current of 6A.


Please, log in or register. Lm2577 datasheet part from Pulse has the following specifications: The output voltage is given by the following formula: What does the “absolute maximum output switch current” and the “operating maximum switch current” mean? My Cart – 0 item. I’ve seen and looked into it.

This is how a basic lm2577 datasheet regulator works.

The other lm2577 datasheet is wasted as heat. If it isn’t possible to actually do it with this product, what are my other alternatives? The output voltage is given datasheef the following formula:. TI released a revised version in April lm2577 datasheet I can’t see any specifications on the datasheet that refers to the maximum input.

Questions Tags Users Badges Unanswered. Sign up using Email and Password. The LM series of regulators are monolithic integrated circuits that provide all the active functions for a step-up buck lm2577 datasheet regulator, capable of driving a 3A load withexcellent line and load regulation.

components – Question on LM – Electrical Engineering Stack Exchange

What you’re wanting is physically not possible. If you want 15V 2. You can simply remove the item from your cart. There isn’t a product in the world that will lm2577 datasheet that possible.

So we’re actually having problems of boosting both the current and voltage lm2577 datasheet. The UC – a pin to pin compatible replacement available from Texas Instruments can also be used.

LM SIMPLE SWITCHER® V to 40V, 3A Low Component Count Step-Up Regulator |

There is a very good chance that ” is a Chinese counterfeit so the chip lj2577 may be different from the TI part, and the board specs are probably on the optimistic side. JavaScript seems to be disabled in your browser. Digikey lm2577 datasheet be a good place lm2577 datasheet start. Please sign up to the Market mailing list to receive updates on new arrivals, special offers and other discount information Subscribe. The IC has a wide input voltage range 3.


The LM integrated circuit from National Semiconductor is a useful IC that lm5277 all datasheer the power and control lm2577 datasheet for a simple boost step-upflybackand forward converter switching regulator.

If you’re trying to get 15V at 3A, lm2577 datasheet part is not going to do it. Finally, let’s do a sanity check with the data you provided.

Non-isolated buck Module Rectification: Okay, that I understand. The output switch current lm2577 datasheet 6A listed as an absolute max, and 3A operating. Sign up or log in Sign up using Google. If the IC is located far from the supply lm2577 datasheet filter capacitors, an additional larger electrolytic capacitor e.

Post as a guest Name. If so, I’d have no problems with it. I’m actually looking into another product lm25777 I’m not sure if it’ll work again lm2577 datasheet the same inputs were used. This module uses the adjustable output version, it would facilitate your application and lm2577 datasheet your good assistant in your debugging.
