Conditions Availablein TO-220 and TO-263 Surface-Mount
Packages Ensured 1-A Output Load Current Input Voltage Range Upto40V Requires Only4 External Components Excellent Line and Load Regulation Specifications 150-kHz Fixed-Frequency Internal Oscillator TTL Shutdown Capability Low Power Standby Mode,IQ, Typically 85 μA High Efficiency Uses Readily Available Standard Inductors Thermal Shutdown and Current-Limit Protection
Applications Simple High-Efficiency Step-Down (Buck)
Regulator Efficient Preregulator for Linear Regulators On-Card Switching Regulators Positive-to-Negative Converter
DescriptionThe LM2595 series of regulators are monolithic
integrated circuits that provideall the active functions
fora step-down (buck) switching regulator, capableof
drivinga 1-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 LM2595 series operatesata switching frequency 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, anda 5-pin TO-263 surface-mount
package. Typically, for output voltages less thanV, and ambient temperatures less than 50°C, no
heat sinkis required.
Device Information(1)(1) Forall available packages, see the orderable addendumat
the endofthe data sheet.
