直流-直流开关降压稳压器, 可调, 4V-60V输入, 3.3V-37V/500mA输出, SOIC-14
Description
The LM2574xx series of regulators are monolithic integrated circuits that provide all the active functions for a step-down buck switching regulator, capable of driving a 0.5-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, 15 V, 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.
