3 Description

The LM2590HV series of regulators are monolithic

integrated circuits that provide all the active functions

for a step-down (buck) switching regulator, capable of

driving a 1-A load with excellent line and load

regulation. These devices are available in fixed output

voltages of 3.3-V, 5-V, and an adjustable output

version.

This series of switching regulators is similar to the

LM2591HV with additional supervisory and control

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 oscillator,

Shutdown/Soft-start, output error flag and flag delay.

The LM2590HV 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 7-pin

TO-220 package with several different lead bend

options, and a 7-pin TO-263 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 90-μA standby current (typical). Self

protection features include a two stage current limit

for the output switch and an over temperature

shutdown for complete protection under fault

conditions.
