General Description
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.
The MIC4575 is available in 3.3V, and 5V fixed output versions or a 1.23V to 20V adjustable output version. Both versions are capable of driving a 1A load with excellent line and load regulation.
Features
? 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 4V to 24V input voltage range
? Wide 1.23V to 20V output voltage range
? Requires minimum external components
? < 200μA 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 3.3V for Intel Pentium? and similar microprocessors
