    | Partname: | SC1109 |  | Description: | SYNCHRONOUS PWM CONTROLLER WITH DUAL LOW DROPOUT REGULATOR CONTROLLERS |  | Manufacturer: | Semtech Corp. |  | Datasheet: | PDF (223K). Click here to download *)
 |  | The SC1109 was designed for the latest high speed motherboards. It combines a synchronous voltage mode controller (switching section) with two low-dropout linear regulator controllers. The voltage mode controller provides the power supply for the system AGTL bus. The 1.8V and 2.5V linear controllers power the Chipset and clock circuitry. |  |  Click here to download SC1109 Datasheet*)
