National P/N LM2592HV - SIMPLE SWITCHER Power Converter 150 KHz 2A Step-Down Voltage Regulator
Other features include a guaranteed ±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 A 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.
