The Primarion Di-POLTM PX7520 Power IC is a highly
configurable Digital Point-of-Load (POL) Controller with two
PWM outputs for use in high current buck converter
topologies. Up to four controllers from the Primarion Di-POL
family can be synchronized for multiphase operation. The
PX7520 provides PMBus™ compliant POL power regulation
and supports current sharing and interleaving of multiple
chips to balance the power supply currents.
The PX7520 utilizes digital technology to implement all
control functions, providing the ultimate in flexibility and
stability. The PX7520 incorporates an industry standard
PMBus™ compliant 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 PX7520 to provide
digitized information for real time system monitoring and
control.
The PX7520 provides superior accuracy through internal
calibration that measures and corrects current sense error
sources upon startup. The PX7520 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.
