LM2595

SIMPLE SWITCHER^®Power Converter 150 kHz

1A Step-Down Voltage Regulator

General Description

Features

n 3.3V, 5V, 12V, and adjustable output versions

The LM2595 series of regulators are monolithic integrated

circuits that provide all the active functions for a step-down

(buck) switching regulator, capable of driving a 1A load with

excellent line and load regulation. These devices are avail-

able in fixed output voltages of 3.3V, 5V, 12V, and an adjust-

able output version.

n Adjustable version output voltage range, 1.2V to 37V

4% max over line and load conditions

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

packages

n Guaranteed 1A output load current

n Input voltage range up to 40V

n Requires only 4 external components

n Excellent line and load regulation specifications

n 150 kHz fixed frequency internal oscillator

n TTL shutdown capability

n Low power standby mode, I_Qtypically 85 µA

n High efficiency

Requiring a minimum number of external components, these

regulators are simple to use and include internal frequency

†

compensation , and a fixed-frequency oscillator.

The LM2595 series operates at a switching frequency of

150 kHz thus allowing smaller sized filter components than

what would be needed with lower frequency switching regu-

lators. Available in a standard 5-lead TO-220 package with

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

surface mount package. Typically, for output voltages less

than 12V, and ambient temperatures less than 50˚C, no heat

sink is required.

n Uses readily available standard inductors

n Thermal shutdown and current limit protection

Applications

A standard series of inductors are available from several dif-

ferent manufacturers optimized for use with the LM2595 se-

ries. This feature greatly simplifies the design of

switch-mode power supplies.

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-

n Positive to negative converter

put voltage under specified input voltage and output load

conditions, and 15% on the oscillator frequency. External

shutdown is included, featuring typically 85 µA stand-by cur-

rent. Self protection features include a two stage frequency

reducing current limit for the output switch and an over tem-

perature shutdown for complete protection under fault condi-

tions.
