LM2576 circuit diagram , Photos and Information

Hey everyone. I hope you will be fine.

Now, today we are going to start something new (yes) friends.

My new topic is LM2576 Circuit diagram , Photos And Information

Summary:

LM2576-5.0 is very simple switching power supply 3A step,down regulator for power digital circuits.

This is a 3A Step-Down Voltage Regulator. Sometimes we need to work on the car or travel outside the area. The without wires internet ADSL. When use the Internet was Using 3G aircards and distributed to the Internet via wireless with “mobile wireless router”. It uses the power supply of 5V 2A. Because it is digital circuit which uses a 10 watt high power ever.

When its used in cars. We can uses power from the cigarette lighter of a car.But have the voltage 12 volts, so it must reduced the voltage down to 5 voltsat current is 2 amperes. We have a lot of choices. When before I use the transistor and IC-7805 for this job. However, when considered with caution. To its low performance. have high temperature and large, as the identity of the generally linear ICs. This work, we try to do the switching IC.

These regulators were designed to minimize the number of external components to simplify the power supply design. Standard series of inductors optimized for use with the LM2576 are offered by several different inductor manufacturers.Since the LM2576 converter is a switch−mode power supply, its efficiency is significantly higher in comparison with popular three−terminal linear regulators, especially with higher input voltages.

 

In many cases, the power dissipated is so low that no heatsink is required or its size could be reduced dramatically.A standard series of inductors optimized for use with the LM2576 are available from several different manufacturers. This feature greatly simplifies the design of switch−mode power supplies.

 

The LM2576 features include a guaranteed ±4% tolerance on output voltage within specified input voltages and output load conditions, and±10% on the oscillator frequency (±2% over 0°C to 125°C). External shutdown is included, featuring 80 A (typical) standby current. The output switch includes cycle−by−cycle current limiting, as well as thermal shutdown for full protection under fault conditions.

I hope it will be helpful for you. Next time I will explain different types of timers which I am going to use for ladder programming and explain how the same types of timer can be used for performing different tasks.
