Produktdetaljer
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
