Features & Applications
The MIC4690YM TR SuperSwitcher™ is an easy-to-use, 500 kHz step-down PWM voltage regulator. The MIC4690 achieves over 1 A of continuous output current over a wide input voltage range in an 8-lead SO (small outline) package.
 
The high switching frequency of the MIC4690 allows the smallest surface-mount inductors and capacitors to be used. Internal compensation ensures fast transient response and a minimum amount of external components.

Features:

  • SO-8 package with over 1 A output current
  • Fixed 500 kHz operation Wide 4 V to 34 V input voltage range
  • Output voltage adjustable to 1.23 V
  • All surface mount solution
  • Internally compensated with fast transient response
  • Up to 85% efficiency
  • Overcurrent protection
  • Frequency foldback short-circuit protection
  • Thermal shutdown

Applications:

  • Simple 1 A step-down (buck) regulator
  • Replacement of TO-220 and TO-263 designs
  • 12 V to 5 V/3.3 V/2.5 V/1.8 V/1.5 V conversion
  • 5 V to 2.5 V/1.8 V/1.5 V conversion
  • On-card switching regulators
  • Hard disk drives
  • Cable modems
  • Positive-to-negative converters
  • Simple battery chargers
