APW7035  
Advanced PWM and Linear Power Control  
Features  
General Description  
The APW7035 integrates PWM controller and linear  
controller , as well as the monitoring and protection  
functions into a single package , which provides two  
controlled power outputs with over-voltage and over-  
current protections. The PWM controller regulates  
the DDR reference voltage (1.25V) or GPU Voltage  
(2.05V) with a synchronous-rectified buck converter.  
The linear controller regulates power for Memory  
Voltage.  
2 Regulated Voltage are provided  
Switching Power for Fixed Voltage (1.25V /  
2.05V) or Adjustable Voltage  
Linear Regulator for FBVDDQ(2.5V)  
Simple Single-Loop Control Design  
Voltage-Mode PWM Control  
Excellent Output Voltage Regulation  
PWM Output : ±1%  
The precision reference and voltage-mode PWM  
control provide ±1% static regulation. The linear con-  
troller drives an external N-channel MOSFET to pro-  
vide adjustable voltage.  
Linear Output : ±3%  
Fast Transient Response  
The APW7035 monitors all the output voltages , and  
a single Power Good signal is issued when the PWM  
Voltage is within ±10% of the DAC setting and the  
Linear regulator output levels are above their under-  
voltagethresholds. Additionalbuilt-inover-voltagepro-  
tection for the PWM output uses the lower MOSFET  
to prevent output voltages above 115% of the DAC  
setting. The PWM over-current function monitors the  
output current by using the voltage drop across the  
upper MOSFET’s RDS(ON) , eliminating the need for a  
current sensing resistor.  
High-Bandwidth Error Amplifier  
Full 0% to 100% Duty Ratio  
Power-Good Output Voltage Monitor  
Over-Voltage and Over-Current Fault Monitors  
Small Converter Size  
Constant Frequency Operation(200kHz)  
Reduce External Component Count  
The APW7035A/B/C/D support a TTL 3-input Digital  
to Analog converter that adjusts the synchronous-  
rectified buck converter output from 1.00V to 3.20V  
, reference to Table1.  
Applications  
Motherboard Power Regulation for Computers  
Low-Voltage Distributed Power Supplies  
VGA Card Power Regulation  
Termination Voltage
