SYSTEM THEORY OF OPERATION
XPhase
TM
Architecture
The XPhase
architecture is designed for multiphase interleaved buck converters which are used in applications
As shown in Figure 2, the XPhase
architecture consists of a Control IC and a scalable array of phase converters
There is no unused or redundant silicon with the XPhase
architecture compared to others such as a 4 phase
TM
requiring small size, design flexibility, low voltage, high current, and fast transient response. The architecture can
be used in any multiphase converter ranging from 1 to 16 or more phases where flexibility facilitates the design
trade-off of multiphase converters. The scalable architecture can be applied to other applications which require
high current or multiple output voltages.
TM
each using a single Phase IC. The Control IC communicates with the Phase ICs through a 5-wire analog bus, i.e.
bias voltage, phase timing, average current, error amplifier output, and VID voltage. The Control IC incorporates all
the system functions, i.e. VID, PWM ramp oscillator, error amplifier, bias voltage, and fault protections etc. The
Phase IC implements the functions required by the converter of each phase, i.e. the gate drivers, PWM comparator
and latch, over-voltage protection, and current sensing and sharing.
TM
controller that can be configured for 2, 3, or 4 phase operation. PCB Layout is easier since the 5 wire bus
eliminates the need for point-to-point wiring between the Control IC and each Phase. The critical gate drive and
current sense connections are short and local to the Phase ICs. This improves the PCB layout by lowering the
parasitic inductance of the gate drive circuits and reducing the noise of the current sense signal.
