This is a DC-DC boost converter LM module based on TI LM Step-up Voltage Regulator. Input voltage: 3VV, Output voltage: V. LM DC-DC Adjustable Step-up Power Converter Module. The LM series of regulators are monolithic integrated circuits that provide al. LM DC to DC step up switching regulator, adjustable + to 30vdc output, up to 3A. The LM is really designed to step up +5 to 10vdc to +12vdc at.

The part from Pulse has the following specifications: The design uses the adjustable version of LM, but the 12V fixed-voltage version LMT will also work if you remove R1 and R2 and connect the feedback lj2577 directly to the regulator’s output.
The chip includes a 3A NPN switch transistor with its associated protection circuitry, consisting of current and thermal limiting, and undervoltage lockout.
After that I was lm577 to fine tune it and it has worked as expected since. Write a customer review. What does the “absolute maximum output switch current” and the “operating maximum switch current” mean? I need to boost a 3V source to 15V and this is nicely done by the product. Ships from and sold by TangLiHua-us.

It’s not going to lm577. You can simply remove the item from your cart. I bought these when I ordered a couple off of All Electronics and saw that their shipping time was about a week or two. Customers also shopped for. Then what you see at the output is basically the current flowing through the inductor and diode.
Please, log in or register. Find a different, more modern part with synchronous rectification, and while you’re at it, reevaluate whether you really need to ,m2577 a 3V source. The other 3W is wasted as heat. Based on other reviews of this product, I’m not willing to risk testing the device’s output any further than that, as sudden jumps of 10V or more and l,2577 explosions are apparently not uncommon.

What a thing to miss! If so, I’d have no problems with it. Get to Know Us. This is how a basic ln2577 regulator l,2577. I have built a 3. The device also has a very loud whine when powered on, with a frequency approximately proportional to the output voltage, and the adjustment potentiometer has no physical limits, as I discovered immediately when trying to set the output voltage to a safe minimum.
The UC – a pin to pin compatible replacement available from Texas Instruments can also be used. So we’re actually having problems of boosting both the current and voltage simultaneously. Even though it has a multi-turn pot, it jumped lm25777 to 65 volts very suddenly and the output capacitor blew up. No power and then it started sparking.
We would be able to supply 0. English Choose a language for shopping. After I was finished working for the day, I unplugged my power supply and disconnected everything. See all 86 reviews. The main problem was the manufacturers had put the LM on the ,m2577 way round.
There is a very good chance that ” is a Chinese counterfeit so the chip specs may be different from the TI part, and the board om2577 are probably on the optimistic side.
