APW7055  
Advanced PWM and Linear Power Controller  
Features  
General Description  
The APW7055 provides the power control and protec-  
tions for two output voltages on M/B DDR applications.  
It integrates one PWM controller , one source-sink  
linear controller(LC) for DDR source-sink purpose, as  
well as the monitor and protection functions into a  
single package. The PWM controller supplies the  
VMEM(2.5V) with a standard buck converter. The  
source-sink linear controller regulates VTT(1.25V)  
power for DDR Termination.  
Operates from 5V input supply  
2 Regulated Voltage are provided  
Standard Buck Switching Power for VMEM  
(2.5V)  
Linear Controller with Source-Sink Regula  
tion for VTT(1.25V)  
Simple Single-Loop Control Design  
Voltage-Mode PWM Control  
Excellent Output Voltage Regulation  
VMEM Output : VMEM ±1.5% Over Tem-per  
ature  
Additional built-in over-voltage protection (OVP) will  
be started when the VMEM output is above 115% of  
the internal DAC setting(VDAC) . OVP function will shut-  
down the upper MOSFET and disable all output volt-  
age . The PWM controller’s over-current function moni-  
tors the output current by sensing the voltage drop  
across the upper MOSFET‘s rDS(ON) , eliminating the  
need for a current sensing resistor .  
VTT Output : 1/2 VIN ±25mV Over Tempera-  
ture  
Fast Transient Response  
Built-in Feedback Compensation  
Full 0% to 100% Duty Ratio  
Over-Voltage and Over-Current Fault Monitors  
Constant Frequency Operation(200kHz)
