Overview
...iption 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.
Additional built-in over-voltage protec...
