LM2593HV
SIMPLE SWITCHER
Power Converter 150 kHz 2A
Step-Down Voltage Regulator, with Features
General Description
The LM2593HV series of regulators are monolithic inte-
grated circuits that provide all the active functions for a
step-down (buck) switching regulator, capable of driving a
2A load with excellent line and load regulation. These de-
vices are available in fixed output voltages of 3.3V, 5V, and
an adjustable output version.
This series of switching regulators is similar to the
LM2592HV with additional supervisory and performance fea-
tures.
Requiring a minimum number of external components, these
regulators are simple to use and include internal frequency
compensation
, improved line and load specifications,
fixed-frequency oscillator, Shutdown/Soft-start, output error
flag and flag delay.
The LM2593HV operates at a switching frequency of 150
kHz thus allowing smaller sized filter components than what
would be needed with lower frequency switching regulators.
Available in a standard 7-lead TO-220 package with several
different lead bend options, and a 7-lead TO-263 Surface
mount package.
Other features include a guaranteed
±
4% tolerance on out-
put voltage under all conditions of input voltage and output
load conditions, and
±
15% on the oscillator frequency. Ex-
ternal shutdown is included, featuring typically 90 μA
standby current. Self protection features include a two stage
current limit for the output switch and an over temperature
shutdown for complete protection under fault conditions.
