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.

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.
