Welcome to Elecrow Online Store. Datashwet 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. We would be able to supply 0.

What I actually need: It’s just making life harder. 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 tried scanning through the datasheet and I fail to see its maximum input current. Post as a guest Name. HenryLachica The seller meant exactly what they said.

But the inductor is one of the most critical components in these types of circuits, so it’s much safer daatsheet simpler to or use ready made off-the shelf parts: I’m trying to work around it. Only datasheft users can write reviews.

components – Question on LM – Electrical Engineering Stack Exchange

dataheet This is your maximum input current. I can’t see any specifications on the datasheet that refers to the maximum input. Okay, that I understand. Finally, let’s do a sanity check with the data you provided. The UC – a pin to pin compatible replacement available from Texas Instruments can also be used.

daasheet Enter your destination to get a shipping estimate. See Matt Young’s answer above. The LM is available in different packages: I only get 0. What does the “absolute maximum output switch current” and the “operating maximum switch current” mean?

So we’re actually having problems of boosting both the current and voltage simultaneously. Even if the switch was up to it, the 3V source would have to supply over 20A. TI released a revised version in April If so, I’d have no problems with it. The schematic is simple, easy to build and cost effective, producing 12V from a 5V unregulated supply with a dattasheet output current of mA. The problem is the current out would not be enough when we use a boost converter.

So if we stack it up, we’re gonna have a total of 4V and 6A, as a source tested the solar cells datasehet a very hot day.

What you’re wanting is physically not possible. If you want 15V 2. The switch switches the input current to ground through the inductor and sense resistor. You can design and make your own inductor using a suitable core recuperated from old equipment if you have the knowledge, practical experience and equipment for this task.

datsaheet Sign up using Facebook. It’s not going to work. If the IC is located far from the supply source filter capacitors, an additional larger electrolytic capacitor e. The supply of our tested solar panel had a voltage of V and a current of 6A.
