♠ TPS74401 3.0-A, Ultra-LDO ene-Programmable Soft-Start
Izilawuli zomugqa ze-TPS74401 low-dropout (LDO) zinikeza isisombululo sokuphatha amandla esiqinile esisebenziseka kalula sezinhlelo zokusebenza ezihlukahlukene. Isiqalo esithambile esingahleleleka sinciphisa ingcindezi kumthombo wamandla okokufaka ngokunciphisa i-capacitive inrush current ekuqaleni kokuqala. I-soft-start i-monotonic futhi ifaneleka kahle ukunika amandla izinhlobo eziningi ezihlukene zamaphrosesa kanye namasekethe ahlanganisiwe aqondene nesicelo (ASICs). Ukunika amandla okokufaka kanye nokuphumayo kwamandla okuhle kuvumela ukulandelana okulula nezilawuli zangaphandle. Lokhu kuvumelana nezimo okuphelele kuvumela umsebenzisi ukuthi alungiselele isisombululo esihlangabezana nezimfuneko zokulandelana ze-fieldprogrammable gate arrays (FPGAs), ama-digital signal processors (DSPs), nezinye izinhlelo zokusebenza ezinezidingo ezithile zokuqalisa.
Isithenjwa esinembayo nesikhulisi sephutha siletha ukunemba okungu-1% phezu komthwalo, ulayini, izinga lokushisa, nenqubo. Umndeni we-TPS74401 wama-LDO uzinzile ngaphandle kwe-capacitor ephumayo noma ngama-ceramic output capacitor. Umndeni wedivayisi ucaciswe ngokugcwele kusukela ku-TJ = -40°C kuya ku-125°C. I-TPS74401 inikezwa ngamaphakeji amancane we-VQFN amaphini angu-20 (i-5-mm × 5-mm RGW kanye nephakheji ye-RGR engu-3.5-mm × 3.5-mm), ekhiqiza usayizi wesixazululo ohlangene kakhulu. Kuzinhlelo zokusebenza ezidinga ukuchithwa kwamandla engeziwe, iphakheji ye-DDPAK (KTW) nayo iyatholakala.
