LM2591HV
SIMPLE SWITCHER® Power Converter 150 kHz 1A
Step-Down Voltage Regulator
General Description

The LM2591HV seriesof regulators are monolithic inte-
grated circuits that provideall the active functionsfora
step-down (buck) switching regulator, capableof drivinga load with excellent line and load regulation. These de-
vices are availablein fixed output voltagesof 3.3V, 5V, and adjustable output version.
This seriesof switching regulatorsis similarto the
LM2590HV, but without someofthe supervisory and perfor-
mance featuresofthe latter.
Requiringa minimum numberof 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
wouldbe needed with lower frequency switching regulators.
Availableina standard 5-lead TO-220 package with several
different lead bend options, anda 5-lead TO-263 Surface
mount package.
Other features includea guaranteed ±4% toleranceon out-
put voltage underall conditionsof input voltage and output
load conditions, and ±15%on the oscillator frequency. Ex-
ternal shutdownis included, featuring typically 90µA
standby current. Self protection features includea two stage
current limitfor the output switch andan over temperature
shutdownfor complete protection under fault conditions.
Features
3.3V, 5V, and adjustable output versions Adjustable version output voltage range, 1.2Vto 57V±4% max over line and load conditions Guaranteed1A output load current Availablein 5-pin TO-220 and TO-263 (surface mount)
Package Input voltage rangeupto 60V 150 kHz fixed frequency internal oscillator On/Off control Low power standby mode,IQ typically90µA High Efficiency Thermal shutdown and current limit protection
Applications
Simple high-efficiency step-down (buck) regulator Efficient pre-regulatorfor linear regulators On-card switching regulators Positiveto Negative converter
