♠ TPS6282x 2.4-V kuya ku-5.5-V Okokufaka, 1-, 2-, 3-, 4-A Isiguquli sokuya phansi esinokunemba okungu-1% kokuphumayo
I-TPS6282x iwumndeni wokuguqula i-DC-DC ovunyelaniswa okulula ukuwusebenzisa onomoya othule ophansi kakhulu ongu-4 μA kuphela. Ngokusekelwe ku-topology ye-DCSControl, inikeza impendulo yesikhashana esheshayo. Ireferensi yangaphakathi ivumela ukulawula i-voltage ephumayo yehle iye ku-0.6 V ngokunemba okuphezulu kwe-voltage yempendulo engu-1% ngaphezu kwezinga lokushisa elihlanganayo lika -40°C kuya ku-125°C. Amadivayisi omndeni ane-pin-topin kanye ne-BOM-to-BOM ahambisanayo. Isixazululo sonke sidinga i-inductor encane engu-470-nH, i-capacitor yokufaka engu-4.7-µF eyodwa kanye ne-10-µF emibili noma i-22-µF ekhiphayo capacitor eyodwa.
I-TPS6282x itholakala ngama-flavour amabili. Esokuqala sihlanganisa imodi yokonga amandla efakwe ngokuzenzakalela ukuze kugcinwe ukusebenza kahle okuphezulu kuze kufike emithwalweni emincane kakhulu yokwelula isikhathi sokusebenza kwebhethri lesistimu. Eyesibili igijima nge-PWM ephoqelelwe egcina imodi yokuqhuba eqhubekayo ukuze kuqinisekiswe ukunyakaza okuncane ku-voltage okukhiphayo kanye nefrikhwensi yokushintsha emiswe ngokwe-quasi-fixed. Idivayisi inesiginali ye-Power Good kanye nesekhethi yangaphakathi ethambile yokuqala. Iyakwazi ukusebenza ngemodi engu-100%. Ngokuvikela amaphutha, ihlanganisa ukuvikelwa kwesekethe emfushane ye-HICCUP kanye nokuvalwa kwe-thermal. Idivayisi itholakala ngephakeji ye-QFN engu-6-pin 1.5 x 1.5-mm, enikeza isisombululo esiphezulu sokuminyana kwamandla.
