SYSTEM THEORY OF OPERATION
PWM Control Method
The PWM block diagram of the XPhase TM architecture is shown in Figure 3. Feed-forward voltage mode control with
trailing edge modulation is used. A voltage-type error amplifier with high-gain (110dB) and wide-bandwidth is used
for the control loop. It is not unity gain stable. The power-stage input voltage is sensed by the IR3513, and optional
phase ICs, to provide feed-forward control. 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 system clock frequency is programmable from 500 kHz to 9 MHZ by an external resistor. The IR3513
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 the IR3513 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 last phase IC (PHSOUT) is connected back to PHSIN of the control IC to complete the loop . During
power up, the IR3513 sends out clock signals from both CLKOUT and PHSOUT pins and detects the feedback at
PHSIN pin to determine the phase number and monitor any fault in the daisy chain loop. Figure 4 shows the phase
timing for a four-phase converter. For single-phase operation, PHSOUT (pin 26) and PHSIN (pin 27) must be
shorted together to prevent an Open Control Loop fault from occurring.
