LM2576 Buck Converter overview

There are also fixed output voltage type and variable output voltage type of Converters available with the same IC. The LM is a voltage Regulator ICit uses the Buck-converter topology to step-down and regulate higher level voltage values to lower level.

The value of the inductor can range from 47uH to uH based on the output required. 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. Meet us at the Embedded Show in Nuremberg ddatasheet 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 llm2576-5.

Also the voltage drop across the diode is less and can allow high current to pass through it. The circuit also deals with high current and hence a suitable high voltage di-electric capacitor with low ESR equivalent series datashet should be chosen.

How to use LM IC? Allied Electronics, Inc 1.

LM Buck Converter equivalents, price and datasheet

It requires are a typical inductor size of 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. LM Buck Converter overview. Using the LM is very easy; it requires only 6 additional components including an inductor which is placed in series lm257-5 the output.


Available Distributors without stock: LM is a Below you can find matching inductors from Wuerth Elektronik calculated on the maximum parameters of LM 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. Link to the most up-to-date LM datasheet and the product page for EVM, tools and support information.

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

A typical application circuit for LM is 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. This pin is provided with the feedback voltage based on which the output is regulated.

Chip One Stop Using a wrong value or low wattage inductor might damage the IC permanently.
