Texas Instruments LM2592HVS-ADJ/NOPB

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 2A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, and an adjustable output version.
This series of switching regulators is similar to the LM2593HV, but without some of the supervisory and performance features of the latter. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, improved line and load specifications, and a fixed-frequency oscillator.
The LM2592HV operates at a switching frequency of 150 kHz, thus allowing smaller-sized filter components than what would be needed with lower-frequency switching regulators. Available in a standard 5-lead package with several different lead bend options, and a 5-lead Surface mount package.
Other features include an ensured ±4% tolerance on output voltage under all conditions of input voltage and output load conditions, and ±15% on the oscillator frequency. External shutdown is included, featuring typically 90 μA standby current. Self-protection features include a two-stage current limit for the output switch and an over-temperature shutdown for complete protection under fault conditions.
