♠ TPS51396A 4.5-V ho 24-V, 8-A Synchronous Step-Down Voltage Regulator e nang le ULQ™ Mode bakeng sa Bophelo bo Atolositsoeng ba Battery
TPS51396A ke sesebelisoa se bolokang chelete e ngata, se nang le matla a phahameng a motlakase, se fetolelang ka mokhoa o phahameng oa synchronous buck converter le li-FET tse kopaneng.
Karolo ea bohlokoa ea TPS51396A ke karolo ea eona ea ULQ (Ultra Low Quiscent) ho nolofalletsa ts'ebetso ea hona joale le e kholo ea ts'ebetso e tlase.Karolo ea ULQ e molemo haholo bakeng sa bophelo bo bolelele ba betri ts'ebetsong ea matla a tlase.TPS51396A e sebetsa ka motlakase oa phepelo ea phepelo ho tloha 4.5 V ho ea ho 24 V. E sebelisa mokhoa oa ho laola DCAP3 ho fana ka karabo e potlakileng ea nakoana, mola o motle, taolo ea mojaro, ha ho hlokahale matšeliso a ka ntle, 'me e tšehetsa tlhahiso e tlaase e lekanang ea letoto (ESR) li-capacitor tse kang polymer e khethehileng le li-ultra-low ESR ceramic capacitor.
TPS51396A e fana ka tšireletso e felletseng ea OVP, UVP, OCP, OTP, le UVLO.E kopantsoe le lets'oao le letle la matla le ts'ebetso ea ho lahla sehlahisoa.
Pini ea MODE ho TPS51396A e ka sebelisoa ho seta Eco-Mode kapa mokhoa oa OOA bakeng sa ts'ebetso ea mojaro o bobebe.Eco-Mode e boloka ts'ebetso e phahameng nakong ea ts'ebetso ea mojaro o bobebe, 'me ts'ebetso ea mokhoa oa OOA e nang le maqhubu a switching a maholo ho feta 25 kHz leha e sa jarolloe.
TPS51396A e ts'ehetsa khetho ea nako e ka hare le kantle ea ho qala ka bonolo.E na le nako e tsitsitseng ea ho qala e bonolo ea 1.3 ms.Haeba ts'ebeliso e hloka nako e telele ea ho qala ka bonolo, pinana ea kantle ea SS e ka sebelisoa ho e fihlela ka ho hokahanya capacitor ea kantle.
TPS51396A e fumaneha ka har'a sephutheloana sa 20-pin 3.0- mm × 3.0-mm HotRod mme mocheso oa mateano o hlalositsoe ho tloha -40 ° C ho isa 125 ° C.
