IR3502
SYSTEM THEORY OF OPERATION
System Description
The system consists of one control IC and a scalable array of phase converters, each requiring one phase IC. The
control IC communicates with the phase ICs using three digital buses, i.e., CLOCK, PHSIN, PHSOUT and three
analog buses, i.e., VDAC, EA, IIN. The digital buses are responsible for switching frequency determination and
accurate phase timing control without any external component. The analog buses are used for PWM control and
current sharing among interleaved phases. The control IC incorporates all the system functions, i.e., VID, CLOCK
signals, error amplifier, fault protections, current monitor, etc. The Phase IC implements the functions required by
each phase of the converter, i.e., the gate drivers, PWM comparator and latch, over-voltage protection, Phase
disable circuit, current sensing and sharing, etc.

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 250kHz to 9MHZ 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
