♠ I-TPS61088 10-A I-Synchronous Boost Converter Ehlanganiswe Ngokugcwele
I-TPS61088 iyisiguquli esinamandla amakhulu, esihlanganiswe ngokugcwele nesishintshi samandla esingu-11-mΩ kanye neswishi yokulungisa engu-13-mΩ ukuze inikeze ukusebenza kahle okuphezulu nesixazululo sikasayizi omncane ezinhlelweni eziphathwayo. I-TPS61088 inobubanzi obubanzi bokufaka kagesi ukusuka ku-2.7 V ukuya ku-12 V ukuze isekele izinhlelo zokusebenza ezineseli elilodwa noma amabhethri e-Lithium amaseli amabili. Idivayisi inamandla okushintsha angu-10-A futhi iyakwazi ukuhlinzeka ngogesi ophumayo ongafika ku-12.6 V.
I-TPS61088 isebenzisa i-topology yamanje yokulawula ephezulu eguquguqukayo ukuze ilawule amandla kagesi okukhiphayo. Esimeni esimaphakathi somthwalo osindayo, i-TPS61088 isebenza kumodi yokushintshanisa ububanzi be-pulse (PWM). Esimeni sokulayisha okulula, idivayisi inamamodi okusebenza amabili akhethwe iphinikhodi ye-MODE. Enye imodi ye-pulse frequency modulation (PFM) yokuthuthukisa ukusebenza kahle futhi enye iphoqelelwa imodi ye-PWM ukugwema izinkinga zohlelo lokusebenza ezibangelwa imvamisa yokushintsha kancane. Imvamisa yokushintsha kumodi ye-PWM iyalungiseka, isuka ku-200 kHz iye ku-2.2 MHz nge-resistor yangaphandle. I-TPS61088 iphinde isebenzise umsebenzi wokuqalisa kancane ohlelekayo kanye nomsebenzi womkhawulo wamanje wokushintsha oshintshwayo. Ngaphezu kwalokho, idivayisi ihlinzeka ngokuvikelwa kokuphuma kwe-overvoltage okukhiphayo okungu-13.2-V, ukuvikela okudlulele komjikelezo nomjikelezo, nokuvikela ukuvala shaqa okushisayo.
I-TPS61088 itholakala ku-4.50-mm × 3.50-mm 20-pin VQFN iphakheji.
