LM2576
52kHz Simple 3A Buck Voltage
Regulator
General Description
The LM2576 series of monolithic integrated circuits provide 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.
These
regulators are simple to use because they require a minimum number of external components and include internal frequency compensation and a fixed-frequency oscillator.
The LM2576 series offers a high efficiency replacement for popular three-terminal adjustabl...
