MILITARY DATA SHEET
SIMPLE SWITCHER(TM) 1A STEP-DOWN HIGH VOLTAGE
REGULATOR
General Description
The LM1575HV regulator is a monolithic integrated circuit that provides all the active
functions for a step-down (buck) switching regulator, capable of driving 1A load with
excellent line and load regulation.
Requiring a minimum number of external components, this regulator is simple to use and
includes internal frequency compensation and a fixed-frequency oscillator.
The LM1575HV offers a high-efficiency replacement for popular three-terminal linear
regulators. It substantially reduces the size of the heat sink, and in many cases no heat
sink is required.
A standard series of inductors optimized for use with the LM1575HV are available from
several different manufacturers. This feature greatly simplifies the design of switch-mode
power supplies.
Other features include a guaranteed +4% tolerance on output voltage within specified input
voltage and output load conditions, and +10% on the oscillator frequency. External
shutdown is included, featuring 50uA (typical) standby current. The output switch includes
cycle-by-cycle current limiting, as well as thermal shutdown for full protection under
fault conditions.
