LM2591HVSNVS074E –MAY 2001–REVISED MAY 2016
LM2591HV SIMPLE SWITCHER® Power Converter 150-kHz, 1-A Step-Down Voltage
Regulator Features 3.3-V, 5-V, and Adjustable Output Versions Adjustable Version Output Voltage Range: 1.2V57V ±4% Maximum Over Line and Load
Conditions Specified 1-A Output Load Current Availablein 5-Pin Package Input Voltage Range Upto60V 150-kHz Fixed Frequency Internal Oscillator ON and OFF Control Low Power Standby Mode,IQ Typically90 μA High Efficiency Thermal Shutdown and Current-Limit Protection
Applications Simple High-Efficiency Step-Down (Buck)
Regulators Efficient Preregulator for Linear Regulators On-Card Switching Regulators Positive-to-Negative Converters
DescriptionThe LM2591HV seriesof 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 3.3 V,5 V, and an adjustable output
version.
This seriesof switching regulatorsis similarto the
LM2590HV, but without someof the supervisory and
control featuresof the latter.
Requiring a minimum number of external
components, these regulators are simpleto use and
include internal frequency compensation, improved
line and load specifications, anda fixed-frequency
oscillator.
The LM2591HV operatesata switching frequencyof
150 kHz, thus allowing smaller sized filter
components than what would be needed with lower
frequency switching regulators. Available in a
standard 5-pin package with several different lead
bend options, anda 5-pin surface mount package.
Device Information(1)(1) Forall available packages, see the orderable addendumat
the endofthe data sheet.
