Line and Load Conditions
excellent line and load regulation. These devices are
available in fixed output voltages of 3.3V, 5V, 12V,
Specified 0.5A Output Current
and an adjustable output version, and are packaged
Available in 8-pin Surface Mount and PDIP-8

package.
Input Voltage Range Up to 60V
This series of switching regulators is similar to the
150 kHz Fixed Frequency Internal Oscillator
LM2594 series, with additional supervisory and
Shutdown /Soft-start
performance features added.

needed.
Simple High-efficiency Step-down (Buck)
A standard series of inductors (both through hole and

greatly
simplifies the design of switch-mode power supplies.
Positive to Negative Converter
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
85
μA standby current. Self
protection features include a two stage current limit
for the output switch and an over temperature

conditions.
The LM2597HV is for use in applications requiring
and input voltage up to 60V.
