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.
