♠ I-TPS6302x Esebenza Kahle Kakhulu I-Single Inductor Buck-boost Converter ene-4-A Switches
Amadivayisi we-TPS6302x ahlinzeka ngesixazululo sokuphakelwa kwamandla emikhiqizweni enikwa amandla yi-alkaline yamaseli amabili noma amathathu, ibhethri ye-NiCd noma ye-NiMH, ibhethri ye-Li-ion eyiseli elilodwa noma i-Li-polymer, ama-supercapacitor noma amanye ama-rail okuhlinzeka. Okuphumayo okungafika ku-3 A kuyasekelwa. Uma usebenzisa amabhethri, angakhishwa aze afike ngaphansi kokungu-2 V. Isiguquli se-buck-boost sisekelwe kufrikhwensi engaguquki, isilawuli se-pulse width modulation (PWM) sisebenzisa ukulungiswa okuvumelanisa ukuze kutholwe ukusebenza kahle okuphezulu. Kumaza okulayisha aphansi, isiguquli singena kumodi yokonga amandla ukuze sigcine ukusebenza kahle okuphezulu ebangeni elibanzi lomthwalo wamanje. Imodi yokonga amandla ingakhutshazwa, kuphoqe isiguquli ukuthi sisebenze ngefrikhwensi yokushintsha engaguquki. Isilinganiso esiphezulu samanje kumaswishi sikhawulelwe kunani elivamile elingu-4 A. I-voltage ephumayo iyahleleka kusetshenziswa isihlukanisi sangaphandle esiphikisayo, noma sigxilwe ngaphakathi ku-chip. Isiguquli singacishwa ukuze kuncishiswe ukuphuma kwebhethri. Ngesikhathi sokuvala, umthwalo uyanqanyulwa ebhethrini.
Amadivayisi we-TPS6302x asebenza ebangeni lokushisa lomoya lamahhala elingu--40°C kuya ku-85°C. Amadivayisi apakishwe kuphakheji ye-VSON engu-14-pin enesilinganiso esingu-3 mm × 4 mm (DSJ).
