The MIC4575 is a series of easy to use fixed and adjustable BiCMOS step-down (buck) switch-mode voltage regulators. The 200kHz MIC4575 duplicates the pinout and function of the 52kHz LM2575. The higher switching frequency may allow up to a 2:1 reduction in output filter inductor size.

Fixed version: ±3% max. output voltage

Adjustable version: ±2% max. feedback voltage

Guaranteed 1A switch current

Fixed 200kHz operation

3.3V, 5V, 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 switch current

Wide input voltage range: 4V to 24V

Wide output voltage range: 1.23V to 20V

Requires minimum external components

< 200μA typical shutdown mode

75% efficiency (adjustable version > 75% typical)

Standard inductors and capacitors are 25% of typical LM2575 values.

Thermal shutdown

Overcurrent protection

100% electrical thermal limit burn-in
