The LM2575 series of monolithic integrated circuits provide all the Active functions for a step-down (buck) switching regulator. Fixed versions are available with a 3.3V, 5V, 12V, or 15V fixed output. Adjustable versions have an output voltage range from 1.23V to 37V.

Additional Features:

3.3V, 5V, 12V, and adjustable output versions

Voltage over specified line and load conditions:

Fixed version: ±3% max. output voltage

Adjustable version: ±2% max. feedback voltage

Guaranteed 1A output current

Wide input voltage range: 4V to 40V

Wide output voltage range: 1.23V to 37V

Requires only 4 external components

52kHz fixed frequency internal oscillator

Low power standby mode IQ typically < 200μA

80% efficiency (adjustable version typically > 80%)

Uses readily available standard inductors

Thermal shutdown and current limit protection

100% electrical thermal limit burn-in
