LM2590HVS-ADJ.

Импульсный понижающий DC-DC стабилизатор, регулируемый, 4.5В-60В (Vin), 1.2В-57В, 1А, TO-263-7.

The LM2590HVS-ADJ is a SIMPLE SWITCHER® step-down Voltage Regulator provides all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation. This series of switching regulators is similar to the LM2591HV with additional supervisory and performance features. Requiring a minimum number of external components, this regulator are simple to use and include internal frequency compensation, improved line and load specifications, fixed-frequency oscillator, shutdown/soft-start, output error flag and flag delay. The LM2590HV operates at a switching frequency of 150kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Other features include a guaranteed ±4% tolerance on output voltage under all conditions of input voltage and output load conditions and ±15% on the oscillator frequency. External shutdown is included, featuring typically 90µA standby current.
