General Description

The LM2594/LM2594HV seriesof regulators are monolithic
integrated circuits that provideallthe active functionsfora
step-down (buck) switching regulator, capableof drivinga
0.5A load with excellent line and load regulation. These de-
vices are availablein fixed output voltagesof 3.3V, 5V, 12V,
andan adjustable output version, and are packagedina
8-lead DIP anda 8-lead surface mount package.
Requiringa minimum numberof external components, these
regulators are simpleto use and feature internal frequency
compensation†,a fixed-frequency oscillator, and improved
line and load regulation specifications.
The LM2594/LM2594HV series operatesata switching fre-
quencyof 150 kHz thus allowing smaller sized filter compo-
nents than what wouldbe needed with lower frequency
switching regulators. Becauseofits high efficiency,the cop-
per tracesonthe printed circuit board are normally the only
heat sinking needed. standard seriesof inductors (both through hole and sur-
face mount types) are available from several different manu-
facturers optimizedfor use withthe LM2594/LM2594HV se-
ries. This feature greatly simplifies the design of
switch-mode power supplies.
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 85μA
standby current. Self protection features includea two stage
frequency reducing current limitforthe output switch andan
over temperature shutdownfor complete protection under
fault conditions.
The LM2594HVisfor applications requiringan input voltageto 60V.
Features
3.3V, 5V, 12V, and adjustable output versions Adjustable version output voltage range, 1.2Vto 37V
(57Vfor theHV version)±4% max over line and load
conditions Availablein 8-pin surface mount and DIP-8 package Guaranteed 0.5A output current Input voltage rangeupto 60V Requires only4 external components 150 kHz fixed frequency internal oscillator TTL Shutdown capability Low power standby mode,IQ typically85μA High Efficiency Uses readily available standard inductors 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 convertor
