LM2576-ADJ DATASHEET PDF

The LM series of regulators are monolithic integrated circuits that provide all the active functions for a step-down buck switching regulator, capable of driving 3A load with excellent line and load regulation. These devices are available in fixed output voltages 12V, 15V, and an adjustable output version. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator. The LM series offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink, and in some cases no heat sink is required.

Using agood layout can solve many problems associated with these types of supplies. The problems due to a badlayout are often seen at high current levels and are usually more obvious at large input to output voltagedifferentials. Some of the main problems are loss of regulation at high output current.

PDF , 9. This becomes more critical for packageshaving very low thermal resistance between junction-to-case such as exposed pad TSSOP. The method is explained in an easy to followstep-by-step manner so that a power supply designer can start performing these measurements in a shortamount of time. PDF , 1. PDF , 3. It will discuss several variations of a layout analyze the results andprovide answers to some common EMI questions such whether or not to use a shielded inductor.

Datasheet Texas Instruments LM2576T-ADJ

This pin is provided with the feedback voltage based on which the output is regulated. The LM is a voltage Regulator IC , it uses the Buck-converter topology to step-down and regulate higher level voltage values to lower level. There are also fixed output voltage type and variable output voltage type of Converters available with the same IC. 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.
