Anpec Electronics APW7047
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. The other standard buck converter (PWM2) regulates the VMEM(2.5V) for the power of DDR memory.| Part No. | APW7047 |

FEATURES
● 3 Regulated Voltages are providedGENERAL DESCRIPTION
One PWM converter (PWM1) regulates the VCORE(1.5V) for the GPU with a SYNC. buck converter. 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 protection (OVP) will be started when the VCORE or VMEM output is above 115% of each DAC setting (VCORE and VMEM). OVP function will shutdown the all output voltages until re-powering on the IC. For each PWM converter, the over-current function monitors the output current by sensing the voltage drop across the MOSFET‘s rDS(ON) , eliminating the need for a current sensing resistor. − SYNC. Buck Converter for VCORE (1.15V~1.50V) − Standard Buck Converter for VMEM (2.40V~2.75V) −Linear Controller with SOURCE-SINK Regulation for VTT(1.25V)●
