Link to the most up-to-date LM datasheet and the product page for EVM, tools and support information.

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. Feature and parameter overview with replacement search.

Below you can find matching inductors from Wuerth Elektronik calculated on the maximum parameters of LM The part from Pulse has the following specifications: The UC – a pin to pin datashest replacement available from Texas Instruments can also be used.

The input voltage from 3. The design uses the adjustable version of LM, lm2577r the 12V fixed-voltage version LMT will also work if you remove R1 and R2 and connect the feedback pin directly to the regulator’s output.


Farnell element14 UK 3. The product counter within the button shows the number of available equivalents and a click on the replacement button shows all possible replacements within a parametric overview.

LM Boost Converter datasheet, price and equivalents

For LM replacement searchselect a main parameter tolerance value and adjust the checkboxes om2577t feature match. The chip includes a 3A NPN switch transistor with its associated protection circuitry, consisting of current and thermal limiting, and undervoltage lockout. Transfer Multisort Elektronik 1. The output voltage is given by the following formula:.

LM Boost Converter Overview. 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. Features of the Boost Converter are fixed 52 kHz switching frequency, a typical inductor size of LM prices and available online distributors.

LM2577 Boost Converter Overview

The input capacitor C1 should be a good quality, low ESR, 0. Available Distributors with stock: LM is a The schematic is simple, easy to build and cost effective, producing 12V from a 5V unregulated supply with a maximum output current of mA.


LM Price breaks and distributor sample stock. Low values of ESR can be achieved by using larger value capacitors or by paralleling multiple smaller-value capacitors. But the inductor is one of the most critical components in these types of circuits, so it’s much safer and simpler to or use ready made off-the shelf parts: The LM is available in different packages: With the help of OEMsecrets we show for all Selectors and products worldwide distributor inventory and prices.

The IC has a wide input voltage range 3. Meet us at the Embedded Show in Nuremberg Fresh Search Replacement Search with. Chip One Stop If the IC is located far from the supply source filter capacitors, an additional larger electrolytic capacitor e. Available Distributors without stock:
