LM2593HV series regulators are monolithic integrated circuits that provide positive buck (buck) switching regulators capable of driving a great line and load regulation for all the functions of a 2A load. These devices are available in 3.3V, 5V, and adjustable output versions with fixed output voltages.
This series of switching regulators is similar LM2592HV more supervision and performance characteristics.
Requiring a minimal 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.
LM2593HV operating switching frequency at 150 kHz, thus enabling smaller sizes with lower frequency switching regulators required filter components. The standard 7-pin TO-220 package differs from several options that result in bending, and the 7-pin TO-263 surface mount package.
Other features include a guaranteed 4% tolerance under all conditions under the input voltage and output load conditions of the ± output voltage, and a frequency of ± 15% for the oscillator. Includes external shutdown with a typical 90μA standby current. Self-protection features include a two-stage current limit, output switch, and complete protection in the event of an over-temperature shutdown fault.
