APW7015  
Advanced PWM and Dual Linear Power Control  
Features  
General Description  
The APW7015 integrates a PWM controller and Dual  
linear controller, as well as the monitoring and pro-  
tection functions into a single package, which pro-  
vides three controlled power outputs with over-volt-  
age and over-current protections. The PWM control-  
ler regulates the DDR reference voltage with a syn-  
chronous-rectified buck converter. The linear control-  
ler regulates power for microprocessor core voltage  
and Memory Voltage.  
3 Regulated Voltage are provided  
Switching Power for VTT(1.25V)  
Linear1 Regulator for FBVDDQ(2.5V)  
Linear2 Regulator for NVVDD(2.05V)  
Simple Single-Loop Control Design  
Voltage-Mode PWM Control  
Excellent Output Voltage Regulation  
TTL Compatible 3-bit digital-to-analog converter  
(DAC) that adjusts the output voltage from 1.3VDC  
PWM Output: ±2% Full Temperature  
Linear Output:±3% Full Temperature  
Fast Transient Response  
to 1.65VDC in 0.05V steps is included in APW7015.  
The precision reference and voltage-mode PWM  
control provide ±2% static regulation. The linear  
controller drives an external N-channel MOSFET to  
provide adjustable voltage.  
High-Bandwidth Error Amplifier  
Full 0% to 100% Duty Ratio  
The APW7015 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  
other output levels are above their under-voltage  
thresholds. Additional built-in over-voltage protec-  
tion 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.  
TTL-Compatible 3-Bit Digital-to-Analog Output  
Voltage Selection  
0.05V Steps from 1.3VDC to 1.65VDC  
Power-Good Output Voltage Monitor  
Over-Voltage and Over-Current Fault  
Monitors Small Converter Size  
Constant Frequency Operation(200kHz)  
Programmable Oscillator from 50kHz to  
1MHz
