There are also fixed output voltage type and variable output voltage type of Converters available with the same IC. Below you can find matching inductors from Wuerth Elektronik calculated on the maximum parameters of LM Using a wrong dahasheet or low wattage inductor might damage the IC permanently.
LM2576 Buck Converter overview
LM Regulator features and specifications Switch mode step down voltage regulator Output Voltage for fixed voltage regulator: The product counter within the button shows the number of datasheer equivalents and a click on the replacement button shows all possible replacements within a parametric overview.
Chip One Stop Meet us at the Embedded Show in Nuremberg Available Distributors without stock: TL — Programmable Reference Voltage.
Available Distributors with stock: Transfer Multisort Elektronik Parameter overview and features with replacement search. LM prices and online available distributors. LM Sample stock and distributor price breaks. This pin is provided with the feedback voltage based on which the output is regulated.
LM2576 Buck Converter overview
Allied Electronics, Inc 1. It requires are a typical inductor size of A typical application circuit for LM is show below. Farnell element14 DE Submitted by admin on 29 July 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. 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. Upto 3A Maximum Input Voltage: For the LM replacement searchplease select a main parameter tolerance value and adjust datssheet checkboxes for feature match. 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.
Using the LM is very easy; it requires only 6 additional components including an inductor which is placed in series with the output. With the help of OEMsecrets we show for all Selectors and products worldwide distributor inventory and prices.
Also the voltage drop across the diode is less and can allow high current to pass through it. Karl Kruse GmbH LM is a The circuit also deals dataseet high current and hence a suitable high voltage di-electric capacitor with low ESR equivalent series resistance should be chosen.
The LM is a voltage Regulator ICit uses the Buck-converter topology to step-down and regulate higher level voltage values to lower level. Microchip Technology Inc 6. Fresh Search Replacement Search with. LM Buck Ln2576-5 overview.
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.
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.
List of equivalents and alternatives. 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.
Solid State Supplies 1. Also a high current will be passing through the indictor and hence the coil should be of high gauge to allow the current datadheet pass through it.
