Solid State Supplies 1. Below you dayasheet find matching inductors from Wuerth Elektronik calculated on the maximum parameters of LM There are also fixed output voltage type and variable output voltage type of Converters available with the same 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.

LM2576 Buck Converter overview

For the LM replacement searchplease select a main parameter tolerance value and adjust the checkboxes for feature match. Microchip Technology Inc 6. Using a wrong value or low wattage inductor might damage the IC permanently. How to use LM IC?

Upto 3A Maximum Input Voltage: Transfer Multisort Elektronik Link to datsaheet most up-to-date LM datasheet and the product page for EVM, tools and support information. Allied Electronics, Inc 1. LM Buck Converter overview. TL — Programmable Reference Voltage. LM Sample stock and distributor price breaks.


LM prices and online available distributors. Also the voltage drop across the diode is less and can allow high current to pass through it.

List of equivalents and alternatives. LM is a Submitted by admin on 29 July LM Regulator features and specifications Switch mode step down voltage regulator Output Voltage for fixed voltage regulator: Using the LM is very easy; it requires only 6 additional components including an inductor which is placed in series with the output. It requires are a typical inductor size of This pin is provided with the feedback voltage based on which the output is regulated.

Available Distributors without stock: 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. The circuit ratasheet deals datasheeg high current and hence a suitable high voltage di-electric capacitor with low ESR equivalent series resistance should be chosen.

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

So if you are looking for llm2576-5 switching step-down regulator with these characteristics to regulate a voltage for your circuit then this IC might be of interest to you.

Karl Kruse GmbH 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.


A typical application circuit for LM is show below. Farnell element14 DE Parameter overview and features with replacement search. Also a high current will be passing through the indictor datasgeet hence the coil should be of high gauge to allow the current to pass through it.

LM2576 Buck Converter overview

The value of the inductor can range from 47uH dataaheet uH based on the output required. 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.

With the help of OEMsecrets we show for all Selectors and products worldwide distributor inventory and prices. The LM is a voltage Regulator ICit uses the Buck-converter topology to step-down and regulate higher level voltage values to lower level.

Available Distributors with stock: 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.
