General Description
The APW7047 provides the power controls and protections for three output voltages on AGP/PCI Graphic Card applications. It integrates two PWM controllers , one SOURCE-SINK linear controller, as well as the monitor and protection functions into a single package. One PWM converter (PWM1) regulates the VCORE(1.5V) for the GPU with a SYNC. buck converter. The other standard buck converter (PWM2) regulates the VMEM(2.5V) for the power of DDR memory. The SOURCE-SINK linear controller control two external MOSFETs to be a linear regulator with the capability of sourcing and sinking current. It regulates the VTT (1.25V) power for DDR Termination voltage.
