General Description

The LM2596 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.

Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation†, and a fixed-frequency oscillator.

Overview

LM2596 SIMPLE SWITCHER Power Converter 150 kHz 3A Step-Down Voltage Regulator December 1997 LM2596 SIMPLE SWITCHER ® Power Converter 150 kHz 3A Step-Down Voltage.
