The LM2576SX-12 from Texas Instruments is a versatile DC-DC switching regulator designed for step-down (buck) conversion. It provides a fixed positive output voltage of 12V and can deliver up to 3A of current. The device operates with an input voltage range from 4V to 40V, making it suitable for a variety of power supply applications.
This regulator utilizes a buck topology and does not incorporate a synchronous rectifier. It operates at a switching frequency of 52kHz and is designed for surface mount installation in a TO-263-6, D²Pak package. The operating temperature range is -40°C to 125°C (TJ).
Key electrical characteristics include its 3A output current capability and a fixed 12V output voltage. The wide input voltage range of 4V to 40V offers flexibility in design. The surface mount package facilitates integration into compact electronic systems.
