LM2598

SNVS125D –MARCH 1998–REVISED MAY 2016

LM2598 SIMPLE SWITCHER Power Converter 150-kHz 1-A Step-Down Voltage Regulator,

With Features

1 Features

3 Description

The LM2598 series of regulators are monolithic

integrated circuits that provide all the active functions

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

driving a 1-A load with excellent line and load

regulation. These devices are available in fixed output

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

version.

•

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

Adjustable Version Output Voltage Range, 1.2-V

to 37-V ±4% Max Over Line and Load Conditions

•

1-A Output Current

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

Mount) Package

The LM2598 is a member of the LM259x family.

•

Input Voltage Range Up to 40 V

Excellent Line and Load Regulation Specifications

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.

Out of Regulation Error Flag

Error Output Delay

Low Power Standby Mode, I_Q, Typically 85 μA

High Efficiency

The LM2598 series operates at a switching frequency

of 150 kHz, thus allowing smaller sized filter

components than what would be required with lower-

frequency switching regulators. Available in

standard 7-lead TO-220 package with several

different lead bend options, and a 7-lead DDPAK

surface mount package. Typically, for output voltages

less than 12 V, and ambient temperatures less than

50°C, no heat sink is required.
