kr LM1575/LM2575/LM2575HV Series SIMPLE SWITCHER 1A Step-Down Voltage Regulator August 2004 LM1575/LM2575/LM2575HV SIMPLE SWITCHER ® 1A Step-Down Voltage Regulator General Description The LM2575 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation.
These devices are available in fixed output voltages of 3.
3V, 5V, 12V, 15V, and an adjustable output version.
Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator.
The LM2575 series 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 LM2575 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 voltages and output load conditions, and ± 10% on the oscillator frequency.
External shutdown is included, featuring 50 µA (typical) standby current.
The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions.
Features n 3.
3V, 5V, 12V, 15V, and adjustable output versions n Adjustable version output voltage range, 1.
23V to 37V (57V for HV version) ± 4% max over line and load conditions n Guaranteed 1A output current n Wide input voltage range, 40V up to 60V for HV version n Requires only 4 external components n 52 kHz fixed frequency internal oscillator n TTL shutdown capability, low power standby mode n High efficiency n Uses readily available standard inductors n Thermal shutdown and current limit protection n P+ Product Enhancement tested...
