the WEBENCH Power Designer
Applications Simple High-Efficiency Step-Down (Buck)
Regulator On-Card Switching Regulators Positiveto Negative Converter
DescriptionThe LM2596 series of regulators are monolithic
integrated circuits that provideall the active functions
fora step-down (buck) switching regulator, capableof
drivinga 3-A load with excellent line and load
regulation. These devices are availablein fixed output
voltagesof 3.3V,5V,12V, and an adjustable output
version.
Requiring a minimum number of external
components, these regulators are simpleto use and
include internal frequency compensation, anda fixed-
frequency oscillator.
The LM2596 series operatesata switching frequency 150 kHz, thus allowing smaller sized filter
components than what would be required with lower
frequency switching regulators. Available in a
standard 7-pin TO-220 package with several different
lead bend options, anda 7-pin TO-263 surface mount
package.
Device Information(1)(1) Forall available packages, see the orderable addendumat
the endofthe data sheet.
