The PX3532 2-phase Digital Power Controller provides
intelligent power for today’s point-of-load power regulation
applications by driving one or two synchronous-rectified
buck-converter channels in parallel. Interleaved timing of the
channels results in a higher switching frequency, reducing
input and output ripple. With up to two phases, each
capable of up to 2MHz operation, the PX3532 can be used
to build DC-DC converters that provide up to 60A with
excellent efficiency, low ripple, and low component count.
The PX3532 utilizes digital technology to implement all
control functions, providing the ultimate in flexibility and
stability. The PX3532 incorporates an industry standard I2C
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 PX3532 to provide digitized information for real
time system monitoring and control.
The PX3532 provides superior accuracy through internal
calibration that measures and corrects current sense error
sources upon startup. The PX3532 has programmable
current sense temperature compensation that allows the
designer to tailor the response for best accuracy over
temperature. Superior accuracy reduces component count
and solution cost.
