LM2575S-12-EV

The LM2575 /LM2575HV series of regulators are monolithic integrated circuits that provide all the active functions for a  step-down (buck) switching regulator, capable of driving a 2A  load with excellent line and load regulation. These devices  are available in fixed output voltages of 3.3V, 5V, 12V, 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 /LM2575HV series operates at a switching frequency of150 kHz thus allowing smaller sized filter compontents than what would be needed with lower frequency  switching regulators. Available in a standard 5-lead TO-220  package with several different lead bend options, and a  5-lesd TO-262 surface mount package.
