APW7047  
Dual Advanced PWM and Source-Sink Linear Controller  
Features  
General Description  
The APW7047 provides the power controls and protec-  
tions for three output voltages on AGP/PCI Graphic Card  
3 Regulated Voltages are provided  
SYNC. Buck Converter for VCORE  
(1.15V~1.50V)  
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 pow-  
er 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 reg-  
ulates the VTT (1.25V) power for DDR Termination voltage.  
Standard Buck Converter for VMEM  
(2.40V~2.75V)  
Linear Controller with SOURCE-SINK  
Regulation for VTT(1.25V)  
Simple Single-Loop Control Design  
Voltage-Mode PWM Control  
Excellent Output Voltage Regulation  
VCORE Output : ±2% Over Temperature  
VMEM Output : ±2% Over Temperature  
VTT Output : 1/2 VIN ±25mV Over  
Temperature Min. VIN = 1.7V  
Fast Transient Response  
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.  
Built-in Feedback Compensation  
Full 0% to 100% Duty Ratio  
Over-Voltage and Over-Current Fault Monitor  
Constant Frequency Operation(200kHz)
