Using a wrong value or low wattage inductor might damage the IC permanently.

Available Distributors without stock: LM Buck Converter overview. Applications Used in battery circuits since they have high efficiency Step-down Linear regulators Used in small SMPS circuits Can also be used to source negative voltage.

Chip One Stop Available Distributors with stock: Meet us at daatsheet Embedded Show in Nuremberg Allied Electronics, Inc 1.

LM2576 Buck Converter overview

There are also fixed output voltage type and variable output voltage type of Converters available with the same IC. The diode 1N is a Schottky diode which can be used with the high switching speed of the regulator IC since it operates at 52kHz. Microchip Technology Inc 6.

A typical application circuit for LM is show below. Dataxheet to the most up-to-date LM datasheet and the product page for EVM, tools and support information.


Farnell element14 DE Below you can find matching inductors from Wuerth Elektronik calculated on the maximum parameters of LM List of equivalents and alternatives.

LM2576 Buck Converter overview

LM Regulator features and specifications Switch mode step down voltage regulator Output Voltage for fixed voltage regulator: Karl Kruse GmbH LM Sample stock and distributor price breaks. LM is a Parameter overview and features with replacement search. Upto 3A Maximum Input Voltage: It requires are a typical inductor size of Transfer Multisort Elektronik LM prices and online available distributors.

This pin is provided with the feedback voltage based on which the output is regulated. TL — Programmable Reference Voltage. Fresh Search Replacement Search with.

Using the LM is very easy; it requires only 6 additional components including an inductor which is placed in series with the output. Solid State Lk2576-5 1. 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. With the help of OEMsecrets we show for all Selectors and products worldwide distributor inventory and prices.

Since this is a switching circuit electrostatic interference should be kept in mind while designing the PCB of placing the components on a perf board.

LM Buck Converter Pinout, Specs, Equivalent, Circuit & Datasheet

So if you are looking for a switching step-down regulator with these characteristics to regulate a voltage for your circuit then this IC might be of interest to you.


The value of the inductor can range from 47uH to uH based on the output required. The circuit also deals with high current and hence a suitable high voltage di-electric capacitor with low ESR equivalent series resistance should be chosen. How to use LM IC?

Again since we are dealing with step-down switching circuit there will high power dissipation and the use of heat sink for the LM is mostly mandatory. Also the voltage drop across the diode is less and can allow high current to pass through it.

Submitted by admin on 29 July The LM is a voltage Regulator ICit uses the Buck-converter fatasheet to step-down and regulate higher level voltage values to lower level. Dataasheet a high current will be passing through the indictor and hence the coil should be of high gauge to allow the current to pass through it.

For the LM replacement searchplease select a main parameter tolerance value and adjust the checkboxes for feature match.
