It requires are a typical inductor size of LM Sample stock and distributor price breaks. This pin is dwtasheet with the feedback voltage based on which the output is regulated.
LM2576 Buck Converter overview
Also 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.
The diode 1N is a Schottky diode which can be used datasheft the high switching speed of the regulator IC since it operates at 52kHz. The value of the inductor can range from 47uH to uH based on the output required. Submitted by admin on 29 July The LM is a voltage Regulator ICit uses the Buck-converter topology to datasheett and regulate higher level voltage values to lower level.
LM Regulator features and specifications Switch mode step down voltage regulator Output Voltage for fixed voltage regulator: LM Buck Converter overview.
Using the LM is very easy; it requires only 6 additional components including an inductor which is placed in series with the output. LM prices and online available distributors. Parameter overview and features with replacement search.
For the LM replacement searchplease select a main parameter tolerance value and adjust the checkboxes for feature match. List of equivalents and alternatives.
LM Buck Converter Pinout, Specs, Equivalent, Circuit & Datasheet
Available Distributors with stock: Datasyeet Search Replacement Search with. Allied Electronics, Inc 1. Also the voltage drop across the diode is less and can allow high current to pass through it. Using a wrong value or low wattage inductor might damage the IC permanently. Transfer Multisort Elektronik Link to the most up-to-date LM datasheet and the product page for EVM, tools and support information. Solid State Supplies 1.
With the help of OEMsecrets we show for all Selectors and products worldwide distributor inventory and prices. How to use LM IC?
Meet us at the Embedded Show in Nuremberg Microchip Technology Inc 6. Karl Kruse GmbH LM is a 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.
Chip One Stop 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. 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.
TL — Programmable Reference Voltage. 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 without stock: 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.
Below you can 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.
LM2576 Buck Converter overview
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. A typical application circuit for LM is show below. Farnell element14 DE Upto 3A Maximum Input Voltage:
