♠ I-TPS53353 Ukusebenza Kakhulu 20-A I-Synchronous Buck SWIFT™ Converter With Ecomode™
I-TPS53353 iyimodi ye-D-CAP™, i-20-A isishintshi esivumelanayo esinama-MOSFET ahlanganisiwe.Idizayinelwe ukuthi isebenziseke kalula, isibalo esiphansi sezingxenye zangaphandle, kanye nezinhlelo zamandla aqaphela isikhala.
Le divayisi inama-MOSFET ahlanganisiwe angu-5.5-mΩ / 2.2-mΩ, u-1% onembile, ireferensi engu-0.6-V, kanye neswishi ye-boost ehlanganisiwe.Isampula yezici ezincintisanayo ihlanganisa: i-conversion input voltage range ukusuka ku-1.5 V ukuya ku-15 V, isibalo sezingxenye zangaphandle esiphansi kakhulu, ukulawulwa kwemodi ye-D-CAP™ yesikhashana esisheshayo, ukusebenza kwemodi ye-auto-skip, isilawuli sokuqala esithambile sangaphakathi, imvamisa ekhethekayo. , futhi asikho isidingo sokunxeshezelwa.
I-voltage yokufaka yokuguqula isuka ku-1.5 V iye ku-15 V, i-voltage yokunikezela isuka ku-4.5 V iye ku-25 V, kanti ububanzi bamandla okukhiphayo busuka ku-0.6 V kuye ku-5.5 V.
Idivayisi itholakala kuphakheji ye-QFN engu-5-mm × 6-mm, 22-pin futhi icaciswa ukusuka ku--40°C kuya ku-85°C.
I-TPS548B28 iyidivayisi entsha ye-20A eyenzelwe izinhlelo zokusebenza zesikhungo sedatha enephakheji elincane, elingena-Pb.
