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.
