IR3510
SYSTEM THEORY OF OPERATION
XPhase
TM
Voltage Regulator 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
be used in any multiphase converter ranging from 1 to 16 or more phases where flexibility facilitates the design
tradeoff 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 an IR3510 Control IC and a scalable array of phase
converters each using a single Phase IC IR3088A. The IR3510 Control IC communicates with the Phase ICs
through a 5?wire analog bus, i.e. bias voltage, reference voltage, phase timing, error amplifier output and average
phase current. The IR3510 control IC has the functions of reference voltage, bias voltage, PWM ramp oscillator,
soft-start, voltage error amplifier, current error amplifier, current limit, current report and fault protections etc. The
IR3088A 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.
