♠ I-TPS65251 4.5-V ukuya ku-18-V Okokufaka, Okuphezulu Kwamanje, Okuvumelanisiwe Kwesinyathelo-Phansi Okuthathu Kwebhaki Nge-FET Ehlanganisiwe
I-TPS65251 ineziguquli ezintathu zokufaka ezibanzi ezivumelanayo ezisebenza kahle kakhulu. Iziguquli zenzelwe ukwenza lula ukusetshenziswa kwazo ngenkathi zinikeza umklami inketho yokwandisa ukusetshenziswa kwazo ngokuya ngohlelo oluqondiwe.
Iziguquli zingasebenza ezinhlelweni ze-5-, 9-, 12- noma 15-V futhi zibe nama-transistors amandla ahlanganisiwe. I-voltage ephumayo ingasethwa ngaphandle kusetshenziswa isihlukanisi esiphikisayo kunoma yiliphi inani eliphakathi kuka-0.8 V futhi eduze nendawo yokufaka. Izici zesiguquli ngasinye zinika amandla iphinikhodi evumela ukuqalisa okulibaziseke ngokwezinjongo zokulandelana, iphinikhodi yokuqala ethambile evumela isikhathi sokuqala esithambile esilungisekayo ngokukhetha i-soft-start capacitor, kanye nephinikhodi yomkhawulo wamanje (RLIMx) evumela umklami ukuthi alungise umkhawulo wamanje ngokukhetha isinqandi sangaphandle futhi alungiselele ukukhetha kwe-inductor. Ukulawulwa kwemodi yamanje kuvumela isinxephezelo se-RC esilula.
Imvamisa yokushintsha yeziguquli ingasethwa nge-resistor yangaphandle exhunywe kuphinikhodi ye-ROSC noma ingavunyelaniswa newashi langaphandle elixhunywe kuphinikhodi ye-SYNC uma kudingeka. Izilawuli ezishintshayo zenzelwe ukusebenza ukusuka ku-300 kHz kuye ku-2.2 MHz. 180° ngaphandle kokusebenza kwesigaba phakathi kweBuck 1 neBuck 2, 3 (I-Buck 2 kanye no-3 egijima esigabeni) kunciphisa izimfuneko zokuhlunga okokufaka.
