LM2574/LM2574HV SIMPLE SWITCHER 0.
5A Step-Down Voltage Regulator June 1999 LM2574/LM2574HV SIMPLE SWITCHER™ 0.
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-efficiency replacement for popular three-terminal linear regulators.
Because of its high efficiency, the copper traces on the printed circuit board are normally the only heat sinking needed.
A standard series of inductors optimized for use with the LM2574 are available from several different manufacturers.
