TEXAS INSTRUMENTS LM2574MX-ADJ/NOPB 直流-直流开关降压逐步递减稳压器, 可调, 4V-40V输入, 1.23V-37V输出, 500mA输出, SOIC-14
The is a SIMPLE SWITCHER® step-down Voltage Regulator for use with on-card switching regulators. The LM2574xx series of regulator is monolithic integrated circuit that provides all the active functions for a step-down buck switching regulator, capable of driving a 0.5A load with excellent line and load regulation. This device is available in fixed output voltages of 3.3, 5, 12, 15V and an adjustable output version. Requiring a minimum number of external components, this regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator. The LM2574xx 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 PCB are normally the only heat sinking needed. A standard series of inductors optimized for use with the LM2574 are available from several different manufacturers.
