APW7046
Dual Advanced PWM and Source-Sink Linear Controller
Features
•
3 Regulated Voltages are provided
General Description
The APW7046 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) supplies the VCORE(1.
5V) for the GPU with a standard 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 an...
