- Efficienciesup to96% inconjunctionwitha digitalpower controllersuch as the UCD9240, UCD9220 or UCD9110 family.The• DigitalI/O PTD08A210W receives controlsignalsfrom the– PWM signal digitalcontrollerand providesparametricand status– FaultFlag(FF) informationback to the digitalcontroller.Together, PowerTrainmodules and a digitalpower controller– Sychronous RectifierEnable (SRE) form a sophisticated,robust,and easilyconfigured• Analog I/O power management solution.– Temperature Operatingfrom an inputvoltagerange of 4.75 V to– Output currrent 14 V, the PTD08A210W providesstep-downpower• SafetyAgency Approvals: conversionto a wide range of outputvoltagesfrom, 0.7V to3.6V. The wide inputvoltagerange makes– UL/IEC/CSA-C22.260950-1 the PTD08A210W particularlysuitableforadvanced• OperatingTemperature:–40°C to85°C computing and server applicationsthat utilizea looselyregulated8-V, 9.6-V or 12-V intermediateAPPLICATIONS distributionbus. Additionally,the wide inputvoltage• DigitalPower Systems range increases design flexibilityby supportingusing UCD9XXX DigitalControllers operation with tightlyregulated 5-V or 12-V intermediatebus architectures. The module incorporatesoutput over-currentand temperaturemonitoringwhich protectsagainstmost load faults.Output currentand module temperature signalsareprovidedforthedigitalcontrollertopermit user defined over-currentand over-temperature warningand faultscerarios. The module uses single-sided,pin-lesssurface mount constructionto providea low profileand compact footprint.The package is lead (Pb) - free and RoHS compatible.
