LM2596 SIMPLE SWITCHER Power Converter 150 kHz

3A Step-Down Voltage Regulator

Check for Samples: LM2596

FEATURES

DESCRIPTION

The LM2596 series of regulators are monolithic

•

3.3V, 5V, 12V, and Adjustable Output Versions

integrated circuits that provide all the active functions

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

driving a 3A load with excellent line and load

regulation. These devices are available in fixed output

voltages of 3.3V, 5V, 12V, and an adjustable output

version.

•

Adjustable Version Output Voltage Range,

1.2V to 37V ±4% Max Over Line and Load

Conditions

•

Available in TO-220 and TO-263 Packages

Ensured 3A Output Load Current

Input Voltage Range Up to 40V

Requiring

minimum number of external

components, these regulators are simple to use and

include internal frequency compensation , and a

fixed-frequency oscillator.

Requires Only 4 External Components

Excellent Line and Load Regulation

Specifications

The LM2596 series 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

Low Power Standby Mode, I_QTypically 80 μA

High Efficiency

standard 5-lead TO-220 package with several

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

surface mount package.

Uses Readily Available Standard Inductors

Thermal Shutdown and Current Limit

Protection

A standard series of inductors are available from

several different manufacturers optimized for use with

the LM2596 series. This feature greatly simplifies the

design of switch-mode power supplies.

APPLICATIONS

•

Simple High-Efficiency Step-Down (Buck)

Regulator

Other features include a ensured ±4% tolerance on

output voltage under specified input voltage and

output load conditions, and ±15% on the oscillator

frequency. External shutdown is included, featuring

typically 80 μA standby current. Self protection

features include a two stage frequency reducing

current limit for the output switch and an over

temperature shutdown for complete protection under
