The LM2576HVSX-12 is a monolithic integrated circuit from Texas Instruments providing a step-down (buck) switching regulator function. It delivers a fixed output voltage with a continuous output current capability of 3A. The device operates at a switching frequency of 52kHz and features a positive output configuration.
The regulator is designed for surface mount assembly in a DDPAK/TO-263-5 package. It operates over a junction temperature range of -40°C to +125°C, making it suitable for industrial and automotive environments. The part does not include a synchronous rectifier.
This regulator is ideal for applications requiring a simple, high-efficiency step-down conversion from a 4V input supply. The fixed output voltage simplifies design by eliminating external feedback components.
