It is a single output, dual channel PolyPhase synchronous step-down DC\/DC controller that drives all N-channel power MOSFET stages. This device includes a high speed differential amplifier for remote output voltage sense. Power loss and supply noise are minimized by operating the two controller output stages out-of-phase and up to 12-phase operation can be achieved. The LTC3856 monitors the output current by sensing the voltage drop across the output inductor (DCR) or by using a sense resistor. DCR temperature compensation maintains an accurate current sense threshold over a broad temperature range. A constant-frequency, current mode architecture allows a phase-lockable frequency of up to 770KHz. Application includes telecom and datacom systems, industrial and medical instruments, DC power distribution systems, computer systems.\u003c\/p\u003e\n  \u003cul\u003e\n   \u003cli\u003ePolyPhase® Controller reduces i\/p and o\/p capacitance and power supply induced noise\u003c\/li\u003e\n   \u003cli\u003eInput voltage range from 4.5 to 38V (TA = 25°C)\u003c\/li\u003e\n   \u003cli\u003eOutput voltage range from 0.6 to 5.0V (TA = 25°C, VIN = 15V)\u003c\/li\u003e\n   \u003cli\u003e±0.75%, 0.6V reference voltage accuracy, high efficiency up to 95%\u003c\/li\u003e\n   \u003cli\u003eProgrammable Burst Mode® operation or stage Shedding� for highest light load efficiency\u003c\/li\u003e\n   \u003cli\u003eActive voltage positioning (AVP), RSENSE or DCR current sensing\u003c\/li\u003e\n   \u003cli\u003eProgrammable DCR temperature compensation\u003c\/li\u003e\n   \u003cli\u003eNominal frequency range from 450 to 550KHz (VFREQ = 1.2V, TA = 25°C)\u003c\/li\u003e\n   \u003cli\u003eAdjustable soft-start or VOUT tracking, stackable for up to 12-phase operation\u003c\/li\u003e\n   \u003cli\u003e32 lead plastic QFN package, operating junction temperature range from -40°C to 125°C\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003ch3\u003eNotes\u003c\/h3\u003e\n  \u003cp\u003eADI products are only authorized (and sold) for use by the customer and are not to be resold or otherwise passed on to any third party\u003c\/p\u003e\n \u003c\/div\u003e\n\u003c\/div\u003e \u003ch4\u003eProduct details\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cdiv\u003e\n \u003cdiv\u003e\n  \u003cdiv\u003e\n   \u003cdiv\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eControl Mode\u003c\/span\u003e\n     \u003cp\u003eCurrent\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eSupply Voltage Max\u003c\/span\u003e\n     \u003cp\u003e38V\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eDuty Cycle (%)\u003c\/span\u003e\n     \u003cp\u003e94%\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eNo. of Pins\u003c\/span\u003e\n     \u003cp\u003e32Pins\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eTopology\u003c\/span\u003e\n     \u003cp\u003eSynchronous Buck (Step Down)\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eOperating Temperature Max\u003c\/span\u003e\n     \u003cp\u003e125°C\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eQualification\u003c\/span\u003e\n     \u003cp\u003e-\u003c\/p\u003e\n    \u003c\/div\u003e\n   \u003c\/div\u003e\n   \u003cdiv\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eSupply Voltage Min\u003c\/span\u003e\n     \u003cp\u003e4.5V\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eNo. of Outputs\u003c\/span\u003e\n     \u003cp\u003e1Outputs\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eIC Case \/ Package\u003c\/span\u003e\n     \u003cp\u003eQFN-EP\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eSwitching Frequency\u003c\/span\u003e\n     \u003cp\u003e770kHz\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eOperating Temperature Min\u003c\/span\u003e\n     \u003cp\u003e-40°C\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eProduct Range\u003c\/span\u003e\n     \u003cp\u003e-\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eSVHC\u003c\/span\u003e\n     \u003cp\u003eNo SVHC (07-Jul-2017)\u003c\/p\u003e\n    \u003c\/div\u003e\n   \u003c\/div\u003e\n  \u003c\/div\u003e\n \u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch4\u003eOther details\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eANALOG DEVICES\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eLTC3856EUH#PBF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003eEach\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTechnical Data Sheet EN\u003c\/td\u003e\n\u003ctd\u003e\u003ca href=\"http:\/\/www.farnell.com\/datasheets\/1957021.pdf\" target=\"_blank\" title=\"View or Download\" download\u003e\u003cimg src=\"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/files\/file_4379f50c-e237-48f9-beae-a4e625c5b304_icon.png?9736775303194905289\" alt=\"Download technical document - datasheet - Tanotis India\" width=\"25\"\u003e\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cbr\u003eAll product and company names are trademarks™ or registered® trademarks of their respective holders.
