SC1109 - Synchronous PWM Controller

Semtech Corporation

Datasheet Details

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 Dual linear controllers power the chip set and clock circuitry. The SC1109A switching section features lossless current sensing, while SC1109C provides programmable over current limit. SC1109 also utilizes latched driver outputs fo.
