Part number : LM2596
Function : SIMPLE SWITCHER Power Converter 150 kHz 3A Step-Down Voltage Regulator
Package information : TO-220 and TO-263 Type
Manufacturer : National Semiconductor
The Regulators 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.
