5A Step-Down
Voltage Regulator
General Description
The LM2574 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 0.
5A load with excellent line and load regulation.
These devices are available in fixed output
voltages of 3.
3V, 5V, 12V, 15V, and an adjustable output version.
Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator.
The LM2574 series offers a high-efficienc...
