illustrate

The LM2593HV series regulators are monolithic integrated circuits that provide positive buck (buck) switching regulators capable of driving an excellent line and load regulation with all the features of a 2A load. These devices are available in fixed output voltages in 3.3V, 5V, and adjustable output versions.

This series of switching regulators is similar to the LM2592HV, which has more 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 oscillators, shutdown/soft start, output error flags, and flag delays.

The LM2593HV operates at a switching frequency of 150 kHz, thus making the filter assembly smaller in size with the lower frequency switching regulator required. The standard 7-pin TO-220 package comes with several different bending options, and the 7-pin TO-263 surface mount package.

Other features include guaranteed 4% tolerance under all conditions under input voltage and output load conditions ± output voltage, and 15% frequency ± oscillator. Includes external shutdown with a typical 90μA standby current. Self-protection features include a two-stage current limit, output switching, and complete protection under overtemperature shutdown fault conditions.
