LM2574HVM-12/NOPB
降压开关稳压器, 固定, 4V-60V输入, 12V与0.5A输出, 52kHZ, SOIC-14
The is a step-down Voltage Regulator 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. It requires a minimum number of external components, it 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. This feature greatly simplifies the design of switch-mode power supplies. Other features include a specified ±4% tolerance on output voltage within specified input voltages and output load conditions and ±10% on the oscillator frequency.
