LM2592HV SIMPLE SWITCHER Power Converter 150 kHz 2A Step-Down Voltage

Regulator

Check for Samples: LM2592HV

FEATURES

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.

•

3.3V, 5V, and Adjustable Output Versions

•

Adjustable Version Output Voltage Range,

1.2V to 57V ±4% Max Over Line and Load

Conditions

•

Ensured 2A Output Load Current

Available in 5-Pin Package

This series of switching regulators is similar to the

LM2593HV, but without some of the supervisory and

performance features of the latter.

Input Voltage Range up to 60V

150 kHz Fixed Frequency Internal Oscillator

On/Off Control

Requiring

minimum number of external

High Efficiency

components, these regulators are simple to use and

include internal frequency compensation†, improved

line and load specifications and a fixed-frequency

oscillator.

Thermal Shutdown and Current Limit

Protection

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.

APPLICATIONS

•

Simple High-Efficiency Step-Down (Buck)

Regulator

•

Efficient Pre-Regulator for Linear Regulators

On-Card Switching Regulators

Other features include a 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.

Positive to Negative Converter

† Patent Number 5,382,918.
