The Primarion Di-POLTM PX7510 Power IC is a highly
configurable Single phase Digital Point-of-Load (POL)
Controller for use in buck converter topologies. Up to four
controllers from the Primarion Di-POL family can be
synchronized for multiphase operation. The PX7510
provides PMBus? compliant POL power regulation and
supports current sharing of multiple chips to balance the
power supply currents.
The PX7510 utilizes digital technology to implement all
control functions, providing the ultimate in flexibility and
stability. The PX7510 incorporates an industry standard
PMBus? 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 PX7510 to provide digitized information
for real time system monitoring and control.
The PX7510 provides superior accuracy through internal
calibration that measures and corrects current sense error
sources upon startup. The PX7510 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.
