Processors that operate above a GHz require fast, intelligent
power systems. The Primarion® PX3535 Digital Multiphase
Controller provides high-bandwidth frequency response,
noise immunity, and active transient performance algorithms
that only digital architecture can provide.
The PX3535 provides core power for today’s high current
microprocessors by driving from one to six synchronousrectified
buck-converter channels in parallel. Interleaved
timing of the channels results in a higher ripple frequency,
reducing input and output ripple. With up to six phases,
each capable of up to 2 MHz operation, the PX3535 can be
used to build DC-DC converters that provide up to 200A with
excellent efficiency, low ripple, and the lowest component
count.
The PX3535 utilizes digital technology to implement all
control functions, providing the ultimate in flexibility and
stability. The PX3535 incorporates an industry standard I2Cbus
serial interface for control and monitoring. Through the
serial interface, the power supply designer can quickly
optimize designs and monitor system performance. The
interface allows the PX3535 to provide digitized information
for real time system monitoring and control.
