Inkcazelo ye-TPS62242
Isixhobo se-TPS6224x sisixhobo sokuguqulela esisebenza ngokugqibeleleyo esihambelanayo se-DC-DC.Isixhobo sibonelela nge-300-mA yemveliso yangoku ukusuka kwiseli ye-Li-Ion enye kwaye ifanelekile kwizicelo eziphathwayo ezisebenza ngebhetri njengeefowuni eziphathwayo kunye nezinye izixhobo eziphathwayo.
Ngoluhlu olubanzi lwe-voltage ye-voltage ye-2 V ukuya kwi-6 V, isixhobo sikwaxhasa i-alkaline yeeseli ezimbini kunye nezintathu, i-3.3-V kunye ne-5-V ye-voltage input rails.
I-TPS6224x isebenza kwi-2.25-MHz i-frequency switching frequency kwaye ingena kwimowudi yokugcina amandla kwimisinga yomthwalo wokukhanya ukugcina ukusebenza okuphezulu kulo lonke uluhlu lwangoku lomthwalo.
Imowudi yokonga amandla ilungiselelwe i-ripple voltage yemveliso ephantsi.Kusetyenziso lwengxolo ephantsi, isixhobo sinokunyanzelwa kwimowudi esisigxina ye-pulse wide modulation (PWM) ngokutsalela i-MODE isikhonkwane phezulu.Kwimowudi yokuvala, ukusetyenziswa kwangoku kuncitshiswe ukuya ngaphantsi kwe-1 µA.I-TPS6224x ivumela ukusetyenziswa kwee-inductors ezincinci kunye ne-capacitors ukufikelela kwisisombululo esincinci.
I-TPS6224x isebenza kuluhlu lobushushu bomoya osimahla obuphakathi -40°C ukuya kuma-85°C.Isixhobo sifumaneka kwi-SOT ye-5-pin kunye ne-6-pin 2-mm × 2-mm iphakheji ye-WSON.
1. Ngoobani abasebenzi kwisebe lakho le-R & D?Ziziphi iziqinisekiso zakho?
-R & D UMlawuli: yenza isicwangciso sexesha elide seR & D senkampani kwaye ubambe isikhokelo sophando kunye nophuhliso;Ukukhokela kunye nokulawula isebe le-r&d ukuphumeza isicwangciso se-r&d yenkampani kunye nesicwangciso sonyaka se-R&D;Lawula inkqubela phambili yophuhliso lwemveliso kwaye uhlengahlengise isicwangciso;Misela uphando lwemveliso egqwesileyo kunye neqela lophuhliso, uphicotho kunye noqeqesho olunxulumene nabasebenzi bobugcisa.
Umphathi we-R & D: yenza imveliso entsha ye-R & D isicwangciso kwaye ubonise ukwenzeka kwesicwangciso;Ukongamela kwaye ulawule inkqubela kunye nomgangatho womsebenzi we-r&d;Phanda ngophuhliso lwemveliso entsha kwaye ucebise izisombululo ezisebenzayo ngokweemfuno zabathengi kwiinkalo ezahlukeneyo
Abasebenzi be-R&d: ukuqokelela kunye nokusombulula iinkcukacha eziphambili;inkqubo yeKhompyutha;Ukuqhuba iimvavanyo, iimvavanyo kunye nohlalutyo;Lungisa izixhobo kunye nezixhobo zovavanyo, iimvavanyo kunye nohlalutyo;Ukurekhoda idatha yokulinganisa, yenza izibalo kwaye ulungiselele iitshathi;Yenza uphando lwamanani
2. Yintoni uphando lwakho lwemveliso kunye nombono wophuhliso?
-Umbono wemveliso kunye nokukhethwa kwemveliso kunye novavanyo lwenkcazo yemveliso kunye noyilo lwesicwangciso seprojekthi kunye novavanyo lwemveliso kunye nokuqinisekiswa kokuqaliswa kwintengiso
