LM2593HV  
SNVS082E –DECEMBER 2001–REVISED MAY 2016  
®
LM2593HV SIMPLE SWITCHER Power Converter 150-kHz, 2-A Step-Down Voltage  
Regulator  
This series of switching regulators is similar to the  
LM2592HV with additional supervisory and  
performance features.

3.3-V, 5-V, and Adjustable Output Versions  
Adjustable Version Output Voltage Range: 1.2 V  
to 57 V ±4% Maximum Over Line and Load  
Conditions  
Requiring minimum number of external  
a
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.

Ensured 2-A Output Load Current  
Available in 7-Pin TO-220 and TO-263 (Surface-  
Mount) Package  
The LM2593HV operates at a switching frequency of  
150 kHz, thus allowing smaller sized filter  
components than what would be needed with lower

lead bend options, and a 7-pin TO-263 surface-mount  
package.  
Out-of-Regulation Error Flag

Low Power Standby Mode: IQ, Typically 90 μA  
High Efficiency  
Other features include a specified ±4% tolerance on  
output voltage under all conditions of input voltage  
and output load conditions, and ±15% on the  
oscillator frequency. External shutdown is included,  
featuring typically 90-μA standby current. Self-  
protection features include a two stage current limit  
for the output switch and an overtemperature  
shutdown for complete protection under fault  
conditions.

3 Description  
The LM2593HV series of regulators are monolithic  
integrated circuits that provide all the active functions  
for a step-down (buck) switching regulator, capable of  
driving a 2-A load with excellent line and load  
regulation. These devices are available in fixed output  
voltages of 3.3-V, 5-V, and an adjustable output  
version.
