LM2591HVSX-ADJ/NOPB | Texas Instruments
Voltage regulators, 5 V, 1.2 V, 57 V
Step-Down Voltage Regulator, LM2591HVSX-ADJ/NOPB, Texas Instruments
The LM2591HVSX-ADJ/NOPB regulator is a monolithic integrated circuit that provides all the active functions for a step-down (buck) switching regulator, capable of driving a 1-A load with excellent line and load regulation. Requiring a minimum number of external components, this regulator is simple to use and includes internal frequency compensation, improved line and load specifications, and a fixed-frequency oscillator. Requiring a minimum number of external components, this regulator is simple to use and includes internal frequency compensation, improved line and load specifications, and a fixed-frequency oscillator. The LM2591HVSX-ADJ/NOPB operates at a switching frequency of 150 kHz, thus allowing smaller sized filter components than what would be needed with a lower frequency switching regulator.
