Introduction

AI Translation

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 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. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed - frequency oscillator. The LM2595 series operates at a switching frequency of 150 kHz, thus allowing smaller - sized filter components than what would be needed with lower - frequency switching regulators. Available in a standard 5 - pin TO - 220 package with several different lead bend options, and a 5 - pin TO - 263 surface - mount package. Typically, for output voltages less than 12 V, and ambient temperatures less than 50°C, no heat sink is required. A standard series of inductors are available from several different manufacturers optimized for use with the LM2595 series. This feature greatly simplifies the design of switch - mode power supplies. Other features include a ±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 standby current. Self protection features include a two stage frequency reducing current limit for the output switch and an overtemperature shutdown for complete protection under fault conditions.
