♠ TPS51396A 4.5-V to 24-V, 8-A Synchronous Step-Down Voltage Regulator enemodi ye-ULQ™ Yempilo Yebhethri Enwetshiwe
I-TPS51396A iyisiguquli esingabizi kakhulu, esinamandla kagesi aphezulu, nesiguquli sebhanti esisebenza kahle kakhulu esinama-FET ahlanganisiwe.
Isici esibalulekile se-TPS51396A isici sayo se-ULQ (Ultra Low Quiscent) ukuze sikwazi ukusebenza ngokuchema okuphansi nokusebenza komsebenzi omkhulu. Isici se-ULQ sizuzisa kakhulu empilweni yebhethri ende ekusebenzeni kwamandla aphansi. I-TPS51396A isebenza nge-voltage yokufaka yokuhlinzeka esukela ku-4.5 V kuya ku-24 V. Isebenzisa imodi yokulawula ye-DCAP3 ukuze inikeze impendulo yesikhashana esheshayo, umugqa omuhle, ukulawulwa komthwalo, asikho isidingo sesinxephezelo sangaphandle, futhi isekela ama-capacitor okukhipha okulingana okulinganayo okuphansi (ESR) njenge-polymer ekhethekile kanye ne-ultra-low capacitors Ceramic ESR.
I-TPS51396A inikeza ukuvikelwa okuphelele kwe-OVP, i-UVP, i-OCP, i-OTP, ne-UVLO. Kuhlanganiswe amandla isignali enhle kanye nomsebenzi wokukhipha okukhiphayo.
Iphinikhodi ye-MODE ku-TPS51396A ingasetshenziselwa ukusetha imodi ye-Eco-Mode noma i-OOA ukuze isebenze ngokulayishwa okukhanyayo. I-Eco-Mode igcina ukusebenza kahle okuphezulu ngesikhathi sokusebenza komthwalo wokukhanya, futhi imodi ye-OOA isebenza ngefrikhwensi yokushintsha enkulu kuno-25 kHz noma ingalayishi.
I-TPS51396A isekela inketho yesikhathi sokuqalisa esithambile yangaphakathi nengaphandle. Inesikhathi sangaphakathi esingaguquki sokuqala esithambile esingu-1.3 ms. Uma uhlelo lokusebenza ludinga isikhathi eside sokuqalisa okuthambile, iphinikhodi ye-SS yangaphandle ingasetshenziswa ukuyifinyelela ngokuxhuma i-capacitor yangaphandle.
I-TPS51396A itholakala kuphakheji ye-HotRod engu-20-pin 3.0- mm × 3.0-mm futhi izinga lokushisa lokuhlangana licaciswe ukusuka ku -40°C kuya ku-125°C.
