DESCRIPTION

ORDERING INFORMATION

The LM2596 series of regulators are monolithic integrated

circuits ideally suited for easy and convenient design of a

step-down switching regulator(buck converter).

All circuits of this series are capable of driving a 3.0A load

with excellent line and load regulation. These devices are

available in fixed output voltages of 3.3V, 5.0V,12V,

and an adjustable output version.

These regulators were designed to minimize the number of external components to simplify the

power supply design. Standard series of inductors optimized for use with the LM2596 are offered

by several different inductor manufacturers.

Since the LM2596 converter is a switch-mode power supply, its efficiency is significantly higher in

comparison with popular three-terminal limear regulators, especially with higher input voltages.

In many cases, the power dissipated is so low that no heatsink is required or its size could

be reduced dramatically. A standard series of inductors optimized for use with the TJ2596 are

available from several different manufacturers. This feature greatly simplifies the design of

switch-mode power supplies. The LM2596 features include a guaranteed +/- 4% tolerance

on output voltage within specified input voltages and output load conditions, and +/-15% on the

oscillator frequency (+/- 2% over 0℃ to 125℃).

External shutdown is included, featuring 80㎂ (typical) standby current. Self protection features include

a two stage frequency reducing current limit for output switch and an over temperature shutdown for complete

protection under fault conditions.
