There are also fixed llm2576-5 voltage type and variable output voltage type of Converters available with the same IC. Parameter overview and features with replacement search.
LM Buck Converter Pinout, Specs, Equivalent, Circuit & Datasheet
LM Regulator features and specifications Switch dataeheet step down voltage regulator Output Voltage for fixed voltage regulator: Also the voltage drop across the diode is less and can allow high current to pass through it. Farnell element14 DE Available Distributors without stock: Using the LM is very easy; it requires only 6 additional components including an inductor which is placed in series with the output.
For the LM replacement searchplease select a main parameter tolerance value and adjust the checkboxes for feature match. LM is a The LM is a voltage Regulator IC xatasheet, it uses the Buck-converter topology to step-down and regulate higher level voltage values to lower level.
LM Buck Converter equivalents, price and datasheet
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. Upto 3A Maximum Input Voltage: With the help of OEMsecrets we show for all Selectors and products worldwide distributor inventory and prices.
Below you can find matching inductors from Wuerth Elektronik calculated on the maximum parameters of LM Link to the most up-to-date LM datasheet and the product page for EVM, tools and support information. This pin is provided with the feedback voltage based on which the output is regulated.

LM2576 Buck Converter overview
LM prices and online available distributors. Using a wrong value or low wattage inductor might damage the IC permanently.
Applications Used in battery circuits since they have high efficiency Step-down Linear regulators Used in small Ddatasheet circuits Can also be used to source negative voltage. A typical application circuit for LM lm257-5 show below.
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.
LM Sample stock and distributor price breaks. The value of the inductor can range from 47uH to uH based on the output required.
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. TL — Programmable Reference Voltage.
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 circuit also deals with high current and hence a suitable high dattasheet di-electric capacitor with low ESR equivalent series resistance should be chosen.
Submitted by admin on 29 July Karl Kruse GmbH It requires are a typical inductor size of 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. Meet us at the Embedded Show in Nuremberg Solid State Supplies 1. 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. LM Buck Converter overview.
