LM2595 Datasheet 1a Step-down Voltage Regulator

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM2595 SIMPLE SWITCHER Power Converter 150 kHz 1A Step-Down Voltage Regulator May 1999 LM2595 SIMPLE SWITCHER ® Power Converter 150 kHz 1A Step-Down Voltage.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LM2595 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1A 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.

Key Features

  • include a guaranteed ± 4% tolerance on output voltage under specified input voltage and output load conditions, and ± 15% on the oscillator frequency. External shutdown is included, featuring typically 85 µA stand-by current. Self protection features include a two stage frequency reducing current limit for the output switch and an over temperature shutdown for complete protection under fault conditions. Features n 3.3V, 5V, 12V, and adjustable output versions n Adjustable version output voltage.
