♠ TPS51396A 4.5-V ki te 24-V, 8-A Tukutahi Whakararu Whakararu Ngaohiko Whakatere me te Aratau ULQ™ mo te roa o te ora o te pākahiko.
Ko te TPS51396A he utu whai hua, he whakauru ngaohiko teitei, he kaitahuri hiko tukutahi me nga FET whakauru.
Ko te ahuatanga matua o te TPS51396A ko tana ahuatanga ULQ (Ultra Low Quiescent) kia taea ai te mahi o naianei me te mahi nui.Ko te ahuatanga ULQ he tino painga mo te roa o te ora o te pākahiko i roto i nga mahi iti.Ko te TPS51396A e mahi ana me te ngaohiko whakauru whakauru mai i te 4.5 V ki te 24 V. Ka whakamahia e ia te aratau mana DCAP3 ki te whakarato i te whakautu tere tere, te raina pai, te whakaritenga kawenga, kaore he whakaritenga mo te utu o waho, me te tautoko i te iti o te raupapa parenga (ESR) putanga. pūnga pūnga iahiko pērā i te waerau motuhake me te ultra-iti pūnga iahiko uku.
Ka whakaratohia e te TPS51396A te whakamarumaru katoa OVP, UVP, OCP, OTP, me UVLO.Kua whakakotahihia te tohu tohu pai me te mahi tuku putanga.
Ka taea te whakamahi i te pine MODE i roto i te TPS51396A ki te whakarite i te aratau Eco-Mode, OOA ranei mo te mahi uta mama.Ko te Eco-Mode e pupuri ana i te tino pai i te wa e mahi ana te kawenga mama, me nga mahi o te aratau OOA me te huringa whakawhiti nui ake i te 25 kHz ahakoa kaore he utaina.
Ko te TPS51396A e tautoko ana i te waahanga o roto, o waho hoki o te waa tiimata ngawari.He 1.3 ms te roa o te timatanga ngawari o roto.Mena ka hiahia te tono kia roa ake te waa tiimata ngawari, ka taea te whakamahi i te titi SS o waho ki te whakatutuki ma te hono i te punga o waho.
Kei te wātea te TPS51396A i roto i te kete 20-pin 3.0-mm × 3.0-mm HotRod me te pāmahana hononga kua tohua mai i –40°C ki te 125°C.
