The PX3532 2-phase Digital Power Controller providesintelligent power for today’s point-of-load power regulationapplications by driving one or two synchronous-rectifiedbuck-converter channels in parallel. Interleaved timing of thechannels results in a higher switching frequency, reducinginput and output ripple. With up to two phases, eachcapable of up to 2MHz operation, the PX3532 can be usedto build DC-DC converters that provide up to 60A withexcellent efficiency, low ripple, and low component count.The PX3532 utilizes digital technology to implement allcontrol functions, providing the ultimate in flexibility andstability. The PX3532 incorporates an industry standard I2Cserial interface for control and monitoring. Through the serialinterface, the power supply designer can quickly optimizedesigns and monitor system performance. The interfaceallows the PX3532 to provide digitized information for realtime system monitoring and control.The PX3532 provides superior accuracy through internalcalibration that measures and corrects current sense errorsources upon startup. The PX3532 has programmablecurrent sense temperature compensation that allows thedesigner to tailor the response for best accuracy overtemperature. Superior accuracy reduces component countand solution cost.
