introduce
The LM2596 series is a 3A current output buck switch integrated voltage regulator chip produced by Texas Instruments (TI), which contains a fixed frequency oscillator (150KHZ) and a reference regulator (1.23v), and has a perfect protection circuit, current limit, heat off circuit and so on. The high efficiency voltage regulating circuit can be constructed by using the device with few peripheral devices. Available are: 3.3V, 5V, 12V and adjustable (-ADJ) and other voltage grade products.
