LM2597/LM2597HV SIMPLE SWITCHER Power Converter 150 kHz 0.5A Step-Down

Voltage Regulator, with Features

Check for Samples: LM2597, LM2597HV

FEATURES

DESCRIPTION

The LM2597/LM2597HV series of regulators are

monolithic integrated circuits that provide all the

active functions for a step-down (buck) switching

•

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

•

Adjustable Version Output Voltage Range,

1.2V to 37V (57V for HV Version)±4% Max Over

Line and Load Conditions

regulator, capable of driving

a 0.5A 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, and are packaged

in an 8-lead PDIP and an 8-lead surface mount

package.

•

Specified 0.5A Output Current

Available in 8-pin Surface Mount and PDIP-8

Package

•

Input Voltage Range Up to 60V

150 kHz Fixed Frequency Internal Oscillator

Shutdown /Soft-start

This series of switching regulators is similar to the

LM2594 series, with additional supervisory and

performance features added.

Out of Regulation Error Flag

Error Output Delay

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.

Bias Supply Pin (V_BS) for Internal Circuitry

Improves Efficiency at High Input Voltages

•

Low Power Standby Mode, I_QTypically 85 μA

High Efficiency

The LM2597/LM2597HV series operates at

Uses Readily Available Standard Inductors

switching frequency of 150 kHz thus allowing smaller

sized filter components than what would be needed

with lower frequency switching regulators. Because of

its high efficiency, the copper traces on the printed

circuit board are normally the only heat sinking

needed.

Thermal Shutdown and Current Limit

Protection

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

LM2597/LM2597HV 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 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 85 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

conditions.

The LM2597HV is for use in applications requiring

and input voltage up to 60V.

†Patent Number 5,382,918.
