MIC4575-3.3BT規(guī)格書詳情

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
