SYSTEM THEORY OF OPERATION
XPhase
TM
Architecture
The
XPhase
TM
architecture is designed for multiphase interleaved buck converters which are used in applications
requiring small size, design flexibility, low voltage, high current and fast transient response. The architecture can
control converters of any phase number 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.
As shown in Figure 1, the
XPhase
TM
architecture consists of a Control IC and a scalable array of phase converters
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.
There is no unused or redundant silicon with the
XPhase
TM
architecture compared to others such as a 4 phase
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.
