Available Distributors with stock: 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: Available Distributors without stock: Features of the Boost Converter are fixed 52 kHz switching frequency, a typical inductor size of 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.

If the IC is located far from the supply source filter capacitors, an additional larger electrolytic capacitor e. Transfer Multisort Elektronik 1.

The UC – a datazheet to pin compatible replacement available from Texas Instruments can also be used. For LM replacement searchselect a main parameter tolerance value and adjust the checkboxes for feature match. Fresh Search Replacement Search with.


The chip includes a 3A NPN switch transistor with its associated protection circuitry, consisting of current and thermal limiting, and undervoltage lockout. LM prices and available online distributors.

Low values of ESR can be achieved by using larger value capacitors or by paralleling multiple smaller-value capacitors. LM Price breaks and distributor sample stock.

The LM is available in different packages: The part from Pulse has the following specifications: Meet us at lm2577g Embedded Show in Nuremberg The output voltage is given by the following formula:. The IC has a wide input voltage range 3. Below you can find matching inductors from Wuerth Elektronik calculated on the maximum parameters of LM The input voltage from 3.

LM2577 Boost Converter Overview

Feature and parameter overview with replacement search. 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 pin directly to the regulator’s output.


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. The schematic is simple, easy to build and cost effective, producing 12V from a 5V unregulated supply with a maximum output current of mA. 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.

The input capacitor C1 should be a good quality, low ESR, 0. With the help of OEMsecrets we show for all Selectors and products worldwide distributor inventory and prices.
