3 Description
The LM2592HV series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 2-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, and an adjustable output version.
This series of switching regulators is similar to the LM2593HV, but without some of the supervisory and control features of the latter.
Requiring a minimum number of external ponents, these regulators are simple to use and include internal frequency pensation, improved line and load specifications, and a fixed-frequency oscillator.
The LM2592HV operates at a switching frequency of 150 k Hz, thus allowing smaller sized filter ponents than what would be needed with lower frequency switching regulators. Available in a standard 5-pin package with several different lead bend options, and a 5-pin surface mount package.
