Features & Applications
The MIC4690YM 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
