LM2592HV

SIMPLE SWITCHER^®Power Converter 150 kHz 2A

Step-Down Voltage Regulator

General Description

current limit for the output switch and an over temperature

shutdown for complete protection under fault conditions.

The LM2592HV series of regulators are monolithic inte-

grated 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 de-

vices are available in fixed output voltages of 3.3V, 5V, and

an adjustable output version.

Features

n 3.3V, 5V, and adjustable output versions

n Adjustable version output voltage range, 1.2V to 57V

4% max over line and load conditions

n Guaranteed 2A output load current

n Available in 5-pin TO-220 and TO-263 (surface mount)

Package

This series of switching regulators is similar to the

LM2593HV, but without some of the supervisory and perfor-

mance features of the latter.

n Input voltage range up to 60V

n 150 kHz fixed frequency internal oscillator

n On/Off control

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.

n Low power standby mode, I_Qtypically 90 µA

n High Efficiency

n 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 TO-220 package with several

different lead bend options, and a 5-lead TO-263 Surface

mount package.

Applications

n Simple high-efficiency step-down (buck) regulator

n Efficient pre-regulator for linear regulators

n On-card switching regulators

Other features include a guaranteed 4% tolerance on out-

put voltage under all conditions of input voltage and output

n Positive to Negative converter

load conditions, and 15% on the oscillator frequency. Ex-

ternal shutdown is included, featuring typically 90 µA

standby current. Self protection features include a two stage
