General Description
The LM2590HV series of regulators are monolithic integrated circuits that provide all the active functions for
a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation.
These devices are available in fixed output voltages of 3.3V, 5V, and an adjustable output version.
This series of switching regulators is similar to the LM2591HV with additional supervisory and performance
features.
Requiring a minimum number of external components, these regulators 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 150 kHz thus allowing smaller sized filter components
than what would be needed with lower frequency switching regulators. Available in a standard 7-lead TO-220
package with several different lead bend options, and a 7-lead TO-263 Surface mount package.
