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
