LM2599 SIMPLE SWITCHER Power Converter 150 kHz 3A Step-Down Voltage Regulator,

with Features

Check for Samples: LM2599

FEATURES

DESCRIPTION

The LM2599 series of regulators are monolithic

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.

•

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

•

Adjustable Version Output Voltage Range,

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

Conditions

•

Ensured 3A Output Current

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

Mount) Package

This series of switching regulators is similar to the

LM2596 series, with additional supervisory and

performance features added.

•

Input Voltage Range Up to 40V

150 kHz Fixed Frequency Internal Oscillator

Shutdown/Soft-start

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, error flag delay and error flag

output.

High Efficiency

The LM2599 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

standard 7-lead TO-220 package with several

different lead bend options, and a 7-lead TO-263

Surface mount package.

APPLICATIONS

•

Simple High-Efficiency Step-down (Buck)

Regulator

A standard series of inductors (both through hole and

surface mount types) are available from several

different manufacturers optimized for use with the

LM2599 series. This feature greatly simplifies the

design of switch-mode power supplies.

•

Efficient Pre-Regulator for Linear Regulators

On-Card Switching Regulators

Positive to Negative Converter

Other features include an 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 80 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
