Part Number : LM2595
Function : LM2595 SIMPLE SWITCHER® Power Converter 150 kHz 1A Step-Down Voltage Regulator
Manufacturers : Texas Instruments
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.
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-lead TO-220 package with several different lead bend options, and a 5-lead TO-263 surface mount package. Typically, for output voltages less than 12V, and ambient temperatures less than 50°C, no heat sink is required.
1. 3.3V, 5V, 12V, and Adjustable Output Versions
2. Ensured 1A Output Load Current
3. Input Voltage Range Up to 40V
