Features
Applications
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 shutdown for full protection under fault
conditions.
