LM Regulator features and specifications Switch mode step down voltage regulator Output Voltage for fixed voltage regulator: Microchip Technology Inc 6. The LM is a voltage Regulator ICit uses the Buck-converter topology to step-down and regulate higher level lm257-5 values to lower level.

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.

A typical application circuit for LM is show below. 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.

Also the voltage drop across the diode is less and can allow high current to pass through it. LM Buck Converter overview. Farnell element14 DE LM prices and online available distributors.

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

There are also fixed output voltage type and variable output voltage type of Converters available with the same IC. Meet us at the Embedded Show in Nuremberg Chip One Stop LM is a For the LM replacement searchplease select a main parameter tolerance value and adjust the checkboxes for feature match.

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.

Available Distributors with stock: Allied Electronics, Inc 1. Fresh Search Replacement Search with. Solid State Supplies 1. 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. 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.

Available Distributors without stock: Below you can find matching inductors from Wuerth Elektronik calculated on the maximum parameters of LM Upto 3A Maximum Input Voltage: TL — Programmable Reference Voltage. Using a wrong value or low wattage inductor might damage the IC permanently.

LM2576 Buck Converter overview

Submitted by admin on 29 July Also a high lm576-5 will be passing through the indictor and hence the coil should be of high gauge to allow the current to pass through it. It requires are a typical inductor size of Transfer Multisort Elektronik With the help of OEMsecrets we show for all Selectors and products worldwide distributor inventory and prices.

The diode 1N is a Schottky diode which dxtasheet be used with the high switching speed of the regulator IC since it operates at 52kHz. Link to the most up-to-date LM datasheet and the product page for EVM, tools and support information. The value of the inductor can range from 47uH to uH based on the output required.

LM Sample stock and distributor price breaks. Karl Kruse GmbH List of equivalents and alternatives. This pin is lm5276-5 with the feedback voltage based on which the output is regulated.

Using the LM is very easy; it requires only 6 additional components including an inductor which is placed in series with the output.

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. How to use LM IC?
