    | Partname: | LTC1778-1 |  
    | Description: | Wide Operating Range, No RSENSE  Step-Down Controller |     
    | Manufacturer: | Linear Technology |  
    | Datasheet: | PDF (303K). Click here to download *) |  
    The LTC1778 is a synchronous step-down switching regulator controller optimized for CPU power. The controller uses a valley current control architecture to deliver very low duty cycles with excellent transient response without requiring a sense resistor. Operating frequency is selected by an external resistor and is compensated for variations in VIN.  |
