    | Partname: | LM3661TL-1.25 |  
    | Description: |  450mA Subminiature, Micropower Step-Down DC-DC Converter for Ultra Low-Voltage Circuits |     
    | Manufacturer: | National Semiconductor |  
    | Datasheet: | PDF (841K). Click here to download *) |  
    The LM3661 step-down DC-DC converter is optimized for powering ultra-low voltage circuits from a single Lithium-Ion cell. The device provides two pin-selectable output voltages. See ordering information for a list of voltage options available . This allows adjustment for DSP or CPU voltage options, as well as dynamic output voltage switching for reduced power  |
