TEXAS INSTRUMENTS LM2590HVS-ADJ. 直流-直流开关降压逐步递减稳压器, 可调, 4.5V-60V输入, 1.2V-57V输出, 1A输出, TO-263-7
The 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.
