illustrate

The regulator's LM2594/LM2594HV series are monolithic integrated circuits that provide positive buck (buck) switching regulators capable of driving an excellent line and load regulation of all the functions of a 0.5A load. These devices are available in fixed output voltages in 3.3V, 5V, 12V and adjustable output versions and are available in an 8-pin DIP package and an 8-pin surface mount package.

Requiring a minimum number of external components, these regulators are simple to use, feature internal frequency compensation †, fixed frequency oscillators, and improved line and load regulation specifications.

The LM2594/LM2594HV series switch at 150 kHz, thus making the smaller size with the lower frequency switching regulator required for the filter assembly. Due to their high efficiency, copper traces of printed circuit boards are often the only heat dissipation needs.

Standard inductor series (through-hole and surface mount types) can be optimized from several different manufacturers from the LM2594/LM2594HV series. This feature greatly simplifies the design of switching power supplies.

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, typically with 85μA standby current. Self-protection features include two-stage frequency reduction output switching and current limiting, complete protection under overtemperature shutdown fault conditions.

The LM2594HV is an application requiring input voltages up to 60V.
