Features & Applications
The MIC4575-5.0WT is a series of easy to use fixed and adjustable BiCMOS step-down (buck) switch-mode voltage regulators. The 200 kHz MIC4575 duplicates the pinout and function of the 52 kHz LM2575. The higher switching frequency may allow up to a 2:1 reduction in output filter inductor size.
The MIC4575 is available in 3.3 V, and 5 V fixed output versions or a 1.23 V to 20 V adjustable output version. Both versions are capable of driving a 1A load with excellent line and load regulation.
Features:
- Fixed 200 kHz operation
- 3.3 V, 5 V, and adjustable output versions
- Voltage over specified line and load conditions:
- Fixed version: ±3% max. output voltage
- Adjustable version: ±2% max. feedback voltage
- Guaranteed 1 A switch current
- Wide 4 V to 24 V input voltage range
- Wide 1.23 V to 20 V output voltage range
- Requires minimum external components
- < 200 μA typical shutdown mode
- 75% efficiency (adjustable version > 75% typical)
- Standard inductors and capacitors are25% of typical LM2575 values
- Thermal shutdown
- Overcurrent protection
- 100% electrical thermal limit burn-in
Applications:
- Simple high-efficiency step-down (buck) regulator
- Efficient pre-regulator for linear regulators
- On-card switching regulators
- Positive-to-negative converter (inverting buck-boost)
- Battery charger
- Negative boost converter
- Step-down 6V to 3.3 V for Intel Pentium® and similar microprocessors
