LM2593HV

SNVS082E –DECEMBER 2001–REVISED MAY 2016

LM2593HV SIMPLE SWITCHER Power Converter 150-kHz, 2-A Step-Down Voltage

Regulator

This series of switching regulators is similar to the

LM2592HV with additional supervisory and

performance features.

1 Features

•

3.3-V, 5-V, and Adjustable Output Versions

Adjustable Version Output Voltage Range: 1.2 V

to 57 V ±4% Maximum Over Line and Load

Conditions

Requiring 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.

•

Ensured 2-A Output Load Current

Available in 7-Pin TO-220 and TO-263 (Surface-

Mount) Package

The LM2593HV operates at a switching frequency of

150 kHz, thus allowing smaller sized filter

components than what would be needed with lower

•

Input Voltage Range up to 60 V

150-kHz Fixed Frequency Internal Oscillator

Shutdown and Soft-Start

frequency switching regulators. Available in

standard 7-pin TO-220 package with several different

lead bend options, and a 7-pin TO-263 surface-mount

package.

Out-of-Regulation Error Flag

Error Flag Delay

Low Power Standby Mode: I_Q, Typically 90 μA

High Efficiency

Other features include a specified ±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 overtemperature

shutdown for complete protection under fault

conditions.

Thermal Shutdown and Current-Limit Protection

2 Applications

•

Simple High-Efficiency Step-Down (Buck)

Regulators

•

Efficient Preregulator for Linear Regulators

On-Card Switching Regulators

3 Description

The LM2593HV series of regulators are monolithic

integrated circuits that provide all the active functions

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

driving a 2-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.

(1) For all available packages, see the orderable addendum at

the end of the data sheet.
