♠ PWM Doubler yokhala ndi mawonekedwe owunikira
ISL6617A imagwiritsa ntchito chiwembu cha Intersil's Phase Doubler kusinthira masitima apamtunda a magawo awiri ndikulowetsa kumodzi kwa PWM. Imachulukitsa kuchuluka kwa magawo omwe olamulira a 3.3V multiphase angathandizire.
ISL6617A idapangidwa kuti ichepetse kuchuluka kwa ma sign a analogi omwe amalumikizana pakati pa owongolera ndi madalaivala pamapulogalamu apamwamba kwambiri owerengera. Chizindikiro chodziwika bwino cha COMP, chomwe nthawi zambiri chimawoneka pamasinthidwe okhazikika, sichifunikira; izi zimathandizira chitetezo chamkokomo ndikuchepetsa masanjidwewo. Kuphatikiza apo, ISL6617A imapereka kuwerengera kwa magawo otsika komanso mwayi wotsika mtengo kuposa njira wamba ya cascaded.
Potsitsa ISL6617A ndi ISL6617 ina kapena ISL6611A, imatha kuwirikiza kanayi kuchuluka kwa magawo omwe olamulira a 3.3V multiphase angathandizire.
ISL6617A imakhalanso ndi zolowetsa ndi zotuluka m'magawo atatu omwe amazindikira kuti ali ndi vuto lalikulu, akugwira ntchito limodzi ndi olamulira a Intersil multiphase PWM ndi masitepe oyendetsa kuti ateteze zowonongeka zowonongeka pamagetsi oyendetsa magetsi pamene ntchito yayimitsidwa. Izi zimathetsa kufunika kwa diode ya Schottky yomwe ingagwiritsidwe ntchito pamagetsi kuti ateteze katunduyo kuti asawonongeke kwambiri.
• Proprietary phase doubler scheme
• Kuwala kokwezeka- mpaka kulemetsa kwathunthu
• Kuwerengera magawo awiri kapena anayi
• Kusanja kwamakono kovomerezeka ndi ma DCR panopa ndi kupindula kosinthika
• Panopa polojekiti linanena bungwe (IOUT) kufewetsa dongosolo mawonekedwe ndi masanjidwe
• yambitsani magawo atatu kuti musankhe
• Ma drive awiri a PWM otulutsa ma milatho awiri okongoletsedwa ndi ma PWM amodzi
• Kulunzanitsa kwa Channel ndi njira ziwiri zolumikizirana
• Kuthandizira kulowetsa kwa 3.3V PWM
• Kuthandizira kutulutsa kwa 5V PWM
• Yogwirizana ndi DCR sensing kapena mwanzeru mphamvu siteji sensing
• Magawo atatu a PWM alowetsa ndi zotuluka kuti atseke siteji
• Chitetezo cha overvoltage
• Phukusi la Dual Flat No-lead (DFN).
- Pafupi ndi gawo la phukusi la chip; imathandizira magwiritsidwe a PCB, mbiri yocheperako
- Zopanda Pb (zogwirizana ndi RoHS)
• Zosintha zamakono, zotsika kwambiri za DC / DC
• Mafupipafupi komanso magwiridwe antchito apamwamba a VRM ndi VRD
• Kuwerengera kwakukulu kwa gawo ndi ntchito zochotsa gawo
• 3.3V PWM cholowetsa chophatikizika cha mphamvu kapena DrMOS
