SYSTEM THEORY OF OPERATION
PWM Control Method
The PWM block diagram of the
XPhase3
TM
architecture is shown in Figure 4. Feed-forward voltage mode control
with trailing edge modulation is used. A high-gain wide-bandwidth voltage type error amplifier in the Control IC is
used for the voltage control loop. Input voltage is sensed in phase ICs and feed-forward control is realized. The
PWM ramp slope will change with the input voltage and automatically compensate for changes in the input voltage.
The input voltage can change due to variations in the silver box output voltage or due to the wire and PCB-trace
voltage drop related to changes in load current.

VCCLDRV
Output of the VCCL regulator error amplifier to control external transistor. The pin
senses 12V power supply through a resistor.
Open collector output that drives low during startup and under any external fault
condition. Connect external pull-up.
The pin configures VIDs for AMD 6-bit, Intel VR11 8-bit with 1.1V Boot voltage, Intel
VR11 8-bit without 1.1V Boot voltage or AMD 5-bit Opteron.
