illustrate
The Regulator LM2590HV Series is a monolithic integrated circuit that provides all buck-active (buck) switching regulators to drive an excellent line and load regulation 1A load capability. These devices are available in fixed output voltage of 3.3V, 5V, and adjustable output versions.
This switching regulator series is LM2591HV to other similar features and performance monitoring.
Requiring a minimum number of external components, these regulators are simple to use, with built-in frequency compensation †, improved line and load specifications, fixed frequency oscillators, shutdown/soft start, output error flags, and flag delays.
The LM2590HV operates at 150 degrees Celsius thus making the small size more than the low-frequency switching regulator that requires a filter element kHz switching frequency. A standard 7-pin TO-220 package offers several different lead bend options, as well as a 7-pin TO-263 surface-mount package.
Other features include a pair of output voltage guaranteed ± all conditions for input voltage and output load conditions and ± 15% oscillator frequency at an error of around 4%. External shutdown is included and has a typical standby current of 90μA. The self-protection feature includes a two-stage output switch and a complete protection, current limit in the event of an over-temperature shutdown fault.
