TPS61175PWPR 3-A , 40V iVoltage High Boost Converter ene-Soft-start kunye neProgrammable Switching Frequency
Iimpawu eziphambili zeTPS61175
I-2.9-V ukuya kwi-18-V Uluhlu lwamandla okufakwayo
3-A, 40-V Ukutshintsha kwangaphakathi
Uguqulo lwamandla aphezulu: Ukuya kuthi ga kwi-93%
Ubungakanani obusetwe ngumxhasi wangaphandle: 200 kHz ukuya kwi-2.2 MHz
I-synchronous yangaphandle yokutshintsha frequency
Isiqalo esithambileyo esichazwe ngumsebenzisi sibe ngumthwalo opheleleyo
Tsiba-ukutshintsha umjikelo wolawulo lwemveliso kumthwalo okhanyayo
14-Pin iphakheji yeHTSSOP enePowerPad™
Yenza uyilo lwesiko usebenzisa i-TPS61175 kunye neWEBENCH uMyili waMandla
Inkcazelo ye-TPS61175
Isixhobo se-TPS61175 sisilawuli sokutshintsha kwe-monolithic kunye ne-3-A edibeneyo, i-40-V powerswitch.Isixhobo sinokuqwalaselwa ngokwemigangatho emininzi yolawulo lwe-topology, kuquka i-boost, i-SEPIC, kunye ne-flyback.Isixhobo sinoluhlu olubanzi lwegalelo lombane ukuxhasa isicelo sombane ongaphakathi kwibhetri ye-multicell okanye elawulwa yi-5-V, i-12-V yeereyili zamandla.
I-TPS61175 ilawula i-voltage ephumayo kunye nemowudi yangoku ye-pulse width modulation (PWM) control.I-frequency switching ye-PWM isetwa yi-resistor yangaphandle okanye i-clocksignal yangaphandle.Umsebenzisi unokucwangcisa i-frequency yokutshintsha ukusuka kwi-200 kHz ukuya kwi-2.2 MHz.
Isixhobo sibonisa umsebenzi wokuqalisa othambileyo ocwangcisekileyo ukunqanda ukungena ngaphakathi ngexesha lokuqalisa, kwaye sinezinye iimpawu zokhuseleko ezakhelwe ngaphakathi, ezifana ne-pulse-by-pulse overcurrent limit kunye nokuvalwa kobushushu.I-TPS61175 ifumaneka kwi-14-pin ye-HTSSOP iphakheji ene-PowerPad.
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
