MIC4574BWM規(guī)格書詳情
General Description
The MIC4574 is a series of easy to use fixed and adjustable BiCMOS step-down (buck) switch-mode voltage regulators. The 200kHz MIC4574 duplicates the pinout and function of the 52kHz LM2574. The higher switching frequency may allow up to a 2:1 reduction in output filter inductor size.
特性 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 0.5A 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 typ.)
? Standard inductors and capacitors are 25 of typical LM2574 values
? Thermal shutdown
? Overcurrent protection
? 100 electrical thermal limit burn-in
Applications
? Simple high-efficiency step-down (buck) regulator
? Efficient preregulator for linear regulators
? On-card switching regulators
? Positive-to-negative converter (inverting buck-boost)
? Isolated flyback converter using minimum external components
? Negative boost converter
