LM2597HVM-ADJ/NOPB, Импульсный понижающий DC-DC стабилизатор, регулируемый, 4.5В-60В (Vin), 1.2В-57В, 500мА, SOIC-8

The LM2597HVM-ADJ/NOPB is a SIMPLE SWITCHER® step-down Voltage Regulator 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 series of switching regulator is similar to the LM2594 series, with additional supervisory and performance features added. Requiring a minimum number of external components, this regulator is simple to use and include internal frequency compensation, improved line and load specifications, fixed-frequency oscillator, shutdown/soft-start, error flag delay and error flag output. The LM2597xx series operates at a switching frequency of 150kHz, thus allowing smaller-sized filter components than what would be required with lower-frequency switching regulators. Because of its high efficiency, the copper traces on the printed-circuit board are normally the only heat sinking required.
