Product Summary

The LM2576-5 is a 52 kHz simple 3A buck voltage regulator. The LM2576-5 provides all the active functions for a step-down (buck) switching regulator. Fixed versions are available with a 3.3V, 5V, or 12V fixed output. Adjustable versions have an output voltage range from 1.23V to 37V. Both versions are capable of driving a 3A load with excellent line and load regulation. The applications of the LM2576-5 include Simple high-efficiency step-down (buck) regulator, Efficient pre-regulator for linear regulators, On-card switching regulators, Positive to negative converter (inverting Buck-Boost), Isolated Flyback Converter using minimum number of external components, Negative Boost Converter.
