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 A
(typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as thermal
