PWM Control Method
The system block diagram of the XPhase3
TM
architecture is shown in Figure 3. 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.
Frequency and Phase Timing Control
The oscillator is located in the control IC and the system clock frequency is programmable from 250 kHz to 9 MHZ by
an external resistor. The control IC system clock signal CLKOUT is connected to CLKIN of all the phase ICs. The
phase timing of the phase ICs is controlled by the daisy chain loop, where control IC phase clock output PHSOUT is
connected to the phase clock input PHSIN of the first phase IC, and PHSOUT of the first phase IC is connected to
PHSIN of the second phase IC, etc. The PHSOUT of the last phase IC is connected back to PHSIN of the control IC.
