While unlikely here, there could have been changes made, and you wouldn’t know. If so, I’d have no problems with it.

If the IC is located far from the supply source filter capacitors, an additional larger electrolytic capacitor e. What you’re wanting is lm25777 not possible. 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 specs are probably on the optimistic side.

I need to boost a 3V source to 15V and this is nicely done by the product. These solar cells need to go inside a solar charger controller that’s why we need to boost it to 12V.

Post as a guest Name. I’ve seen and looked into it.

So what did the seller mean by Input Current: I only get 0. Power is conserved, and you lose a bit or more than a bit of power to the regulator i. The maximum switch current is exactly that: The output voltage is given by the following formula:.

Our price is lower than the manufacturer’s “minimum advertised price. Email Required, but never shown.

But the current isn’t the same because I need about 2. Non-isolated buck Module Rectification: The IC has a wide input voltage range 3.

I’m trying to work around it. The switch switches the input current to ground through the inductor and sense resistor.

If you’re trying to get 15V at 3A, this part is not going to do it. We will use solar panels so that datsaheet do it. The chip includes a 3A NPN switch transistor with its associated protection circuitry, consisting of current and thermal limiting, and undervoltage lockout. With the solar panel, it’s actually possible to have that kind of supply.

First, always get your datasheet straight from the manufacturer. 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. Digikey might be a good place to start.

Only registered users can write reviews. 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.

It’s a good habit to get into. Low values dataasheet ESR can be achieved by using larger value capacitors or by paralleling multiple smaller-value capacitors. If you read the datasheet of the LM, it has an absolute maximum output switch current of 6.
